Have a look at the flags below and tell me how many lines of symmetry they have. Explain how you know.

**Switzerland Czech Republic**

**Somalia Vanuatu**

**Cambodia Nigeria**

Switzerland Flag 🇨🇭

The Switzerland flag is the only flag which is a square so this means it can have a few lines of symmetry including diagonally, horrizantly and vertically. Switzerland’s flag has 4 lines of symmetry and is the only flag which has 4 as they are all rectangles. It has 4 lines because it is a square.

Czech Republic 🇨🇿

Czech Republic only has 1 line of symmetry and that is horizanntlly this is because it can’t have diagonally as it is a rectangle and if it had it vertically it would not be symmetrical as the blue part would not be on both the sides.

Somalia 🇸🇴

Somalia only has 1 line of symmetry and it is vertical. It can not have a horizontal line as the bottom part of the flag would not have a point and the top part would have a point therefore it would not be symmetrical.

Vanuatu 🇻🇺

Vanuatu has 0 lines of symmetry as I can not do it vertically as it would have too black and yellow symbol on the opposite side and if I did it horizontal it would still not work because it would have a swirly bit at the end .

Cambodia 🇰🇭

Cambodia has 1 line of symmetry and it is vertically. I can not do it horizontally because then it would have stairs at the bottom and buildings at the top.

Nigeria 🇳🇬

Nigeria has 2 lines of symmetry vertically and horizontally

1)On the Switzerland flag of t has three lines of symmetry one vertically and one horizontally and another one vertically I know this because if you do any of this then it would still turn out symmetrical

2)on the Czech Republic flag ,it has one line of symmetry which is vertically I know this because when i tried it out I only found one line of symmetry.

3)On the Somali a flag it has two lines of symmetry one vertically and one horizontally I know this because I tried it out with a rulla and I could only see two lines of symmetry.

4)on the Vanuatu flag it has 0 lines of symmetry I know this because when I put the rulla different ways it was very hard to find lines of symmetry so that gave me that idea that that there is no lines of symmetry

5)on the combodia flag there’s one line of symmetry and it goes vertically I know this because when I put the rulla different ways it was heard to see but when I put it vertically it was easy.

6)on the Nigeria flag it has two lines of symmetry and it goes horizontally and vertically I know this because I first tried horizontally and vertically because most of them are like that and then I saw that it was that.

Switzerland has 4 lines of symmetry because it’s a square and a line of symmetry is horizontally,one is vertically and two are from corner to other.

Czech Republic has 2 lines of symmetry because it’s a rectangle and one line is

horizontally and the other one is vertically.

Somalia only has one line of symmetry and that is vertically.

Vanuatu has only one line of symmetry and it’s horizontally.

Nigeria has 2 lines of symmetry and one is horizontally and the other one is vertically

Cambodia has one line of symmetry because it’s only horizontally

1)Has 4 lines of symmetry I know this because if you fold it it will stay the same and if you put a mirror on it it will show it the same.If there was not a cross ther will be more then four symmetrycal Line.

2)It has only 1line of symmetry I Know this because the star can not be halfed more than one time.

3)There is only one line of symmetry I know this because the house can not be halfed more than one time.

4)This flag has no symmetry lines.

5)This flag has no symmetry lines.

6)This has only 4 lines of symmetry because the colour can be halfed.

The Switzerland flag has 4 lines of symmetry . This is because all squares have 4 lines of symetry . One is vertical, one is horizontal , one is diagonal and the last one is the opposite diagonal side.

The Czech Republic flag has 0 lines of symetry. I know this because it has more than one couler that means ther is no chance of symetry.

The Somalia Flag has only 5 lines of symetry. I know this because in a 5 point star there is always 5 lines of symetry so in this flag there is 5 lines of symetry.

The Nigeria flag has 0 lines of symetry. I know this because there is one symbol on the right side and if u split it it will still be on the right.

The Cambodia flag has 1 lines of symetry. This is because you can only split it vercally.

Switzerland has four lines of symmetry on vertical two diagonal and one horizontal because it is the only flag that is square and the cross can have a symmetry lie on each end and corner.

The Czech Republic flag has no symmetry lines because of the different colours and it can’t go vertically because the blue triangle.

The Somalia flag only has one vertical line of symmetry.

The Vanuatu flag has no lines of symmetry.

The Cambodia flag has only one line of symmetry that is vertical.

The Nigeria flag has two lines of symmetry horizontal and vertical.

Switzerland has 4 lines of symmetry because 1 vertical 1 horizontal diagonal this way \ and another diagonal this way /.

Czech Republic has no lines of symmetry because the colours are not the same.

Somalia has 5 lines of symmetry because it has 5 points.

Vanuatu has no lines of symmetry because it has a lot of different colours.

Cambodia has 1 line of symmetry because it is vertical.

Nigeria has 1 line of symmetry because it has 1 vertical line in the middle

1)Switzerland

It has 4 lines of symmetry because the is 1 vertically,horizontally,and 2 sides of diagonally.It has 4 lines of symmetry because all the 4 lines of symmetry,they ar e all the same.

2)Czech Republic

The Czech Republic flag has 0 lines of symmetry because you cannot have a line vertically,diagonally or even horizontally because otherwise alll the lines would not be the same on each side.

3)Somalia

Somalia has 1line of symmetry ,it is vertical because ,if there was a line that was horizontal then the 2 sides would not be the same.The star ruins it all because the star has 5 points like a cone and 5 is an odd number.

4)Vanuatu

Vanuatu has 0 lines of sym because if you put it vertically because of the triangle the sides would be different ,because the triangle is on one sides but not on the other.For a flag to be symmetrical, it has to be the same on both sides .If the flag was symmetrical horizontally the little sign known as a trumpet is not symmetrical because it swirls up like a ball and the Brocken off bit ends at the bottom but not at the top.It would not be diagonal because the colou in the flag on either side on the left are green and red,not the same.

5)Cambodia

Cambodia has 1 line of symmetry for,it cannot be diagonal because the pattern and colours would not be the same on bother sides and symmetrical means to be the same on bothe sodes.It cannot be horizontal for the bottom of the castle sign in the middle does not have turrets at the bottom it has a flat surface so,it cannot be symmetrical horizontal.Overall it has 1 line which is vertical.

6)Nigeria

Nigeria has 2 lines of symmetry because 1 is horizontal and 1 is vertical.Another line of symmetry is not diagonal because the amount of colour would not be the same on each side.

Switzerland has four because it is a square one vertical, one horizontal two diagonal.

Czech Republic has zero lines of symmetry because there is white on one side red on the other side.

Somalia has

The Switzerland flag has 4 lines of symmetry.This is because the flag is a square shape and that means it can go horizontally,vertically and diagonally.I has two lines of symmetry also because if you were to put a of those positions then it would be the same on both sides.The Czech Republic flag has got no lines of symmetry.This is because of the shape and the fact that you can not put a line diagonally.Moreover the pattern and the colours means that if you were to divide the the flag horizontally or vertically once side would have something that the other does not.The Somalian flag has 1 line of symmetry.This is because of the rectilinear shape and that means you can’t have a line of symmetry diagonally.As well as the shape you cannot have a or horizontal line of symmetry as the star has 5 points resulting in the top side having 3 sides and the bottom having 2.The Vanuatu flag has 0 lines of symmetry.It is the same as the Czech flag and can’t have a line of symmetry vertically or horizontally because of the pattern.It is also the same thing with the rectilinear shape.The Cambodian shape has one line of symmetry.As first thing like always it can’t have a symmetrical line diagonally?Another thing is that if you were to divide it horizontally the top of the trees would be on one side and the bottom of the tree would be on the other.The Nigerian flag has two lines of symmetry.The reason it has only two not four lines of symmetry is because of the rectangular shape in result making it impossible to have a symmetrical line diagonally.However you can still have line horizontally and vertically and both sides would be the same.

Switzerland has 4 lines of symmetry because it is the only square flag so you put a line horizontaly,verticaly and verticaly.

Czech Republic has 0 lines of symmetry because it has different colours meaning that if you put a line horizontaly it won’t be symmetrical because the top white and the bottom is red.

Somalia Has 1 line of symmetry which is down the middle because it’s is a star so if you put a line down the middle it will be symmetrical.

Vanuatu has 0 lines of symmetry because if you do it horizontally it won’t work due to the colours and you can’t do it vertically because the shape of the flag and also the colour and there is a decoration where the black colour is.

Cambodia has 1 line of symmetry down the middle because there is a main building in the middle and next to the building is a small building so if you put a line in the middle it will be symmetrical.

Nigeria has 2 lines of symmetry 1 line horizonly because and one is vertically.

1)The first one has 4 lines of symmetry.You can go horizontally,verticaly and diagonally.

2)The second one has 0 lines of symmetry because the colours are not the same.

3)The third one has 1 line of symmetry because you can go vertically.

4)The fourth flag has 0 lines of symmetry because it is not equal.

5)The fifth flag has 1 line of symmetry because you can do it vertically.

6) The sixth flag has 1 line of symmetry because you can do it horizontally.

1)Switzerland

It has 4 lines of symmetry because the is 1 vertically,horizontally,and 2 sides of diagonally.It has 4 lines of symmetry because all the 4 lines of symmetry,they ar e all the same.

2)Czech Republic

The Czech Republic flag has 0 lines of symmetry because you cannot have a line vertically,diagonally or even horizontally because otherwise alll the lines would not be the same on each side.

3)Somalia

Somalia has 1line of symmetry ,it is vertical because ,if there was a line that was horizontal then the 2 sides would not be the same.The star ruins it all because the star has 5 points like a cone and 5 is an odd number.

4)Vanuatu

Vanuatu has 0 lines of sym because if you put it vertically because of the triangle the sides would be different ,because the triangle is on one sides but not on the other.For a flag to be symmetrical, it has to be the same on both sides .If the flag was symmetrical horizontally the little sign known as a trumpet is not symmetrical because it swirls up like a ball and the Brocken off bit ends at the bottom but not at the top.It would not be diagonal because the colou in the flag on either side on the left are green and red,not the same.

5)Cambodia

Cambodia has 1 line of symmetry for,it cannot be diagonal because the pattern and colours would not be the same on bother sides and symmetrical means to be the same on bothe sodes.It cannot be horizontal for the bottom of the castle sign in the middle does not have turrets at the bottom it has a flat surface so,it cannot be symmetrical horizontal.Overall it has 1 line which is vertical

1) The Switzerland flag has 4 lines of symmetry, i know this because if you put a mirror vertically and horizontally it will be the same on each side. Also when you put the mirror through diagonally it will be the same on the other side .

2) The Czech Republic flag has no lines of symmetry because they are all different colours and if you put a mirror through it then it will not be symmetrical because the blue will hit the red and white.

3) The Somalia flag only has 1 line of symmetry because the star in the middle only has 1 line of symmetry and if the star wasn’t there then it would have four lines of symmetry so there is only one vertically line of symmetry so you can’t put a diagonally or horizontally line.

4) The Vanuatua flag has no lines of symmetry because it has all different colours so if you put in horizontally , diagonally or vertically it will be different on all side because they are all different colours.

5) The Cambodia flag has 4 lines of symmetry because the church is all symmetrical and if you put a mirror through it vertically and horizontally then it will be same on each side due to the building in the middle being symmetrical and if you put it diagonally it will not be on symmetrical.

6) The Nigeria flag has 2 lines of symmetry because if you put a mirror through it vertically and horizontally then it will be same on each side whereas if you put the mirror diagonally it will not be the same on each side because a rectangle doesn’t have 4 lines of symmetry .

The Switzerland flag has 4 lines of symmetry.The lines of symmetry are a line going vertically a line going horizontally and the two line that go diagonally.It has 4 line of symmetry because it is a square.

The Czech Republic flag has 1 line of symmetry.The line is a line going horizontally.There is no other line symmetry because if you do it vertically the colours don’t match the other side.

Somalia flag has 1 lines of symmetry.The line symmetry are a line line going horizontally.It doesn’t have line boing diagonally because it is a rectangle.

The Vanuatu flag has 0 lines of symmetry.Because when horizontally vertically or diagonally because the colours and shapes are different.

The Cambodia has 0 lines of symmetry because the stair in the flag is going up it is not at the same height so that’s why it is not a symmetry flag.

The Nigeria flag has 2 lines of symmetry.One line is going horizontally and the another is going vertically.It can’t go diagonally because it is a rectangular flag.

1)Switzerland: The Switzerland flag only has two symmetry line one is horizontally

And the other vertically.

2)Czech republic:Czech republic doesn’t have any lines of symmetry as if you do it vertically as there is a triangle on the left and rectangles on the right making it not symmetrical.

3)Somalia:Somalia is only symmetrical vertically not horizontally because you can’t divide the star up you can only have a star in the middle of a rectangle vertically.

4)Vanuatu : Vanuatu is not symmetrical as there are a triangle on the left and a symbol in the middle and on the right there are two rectangles.

5)cambodia: Cambodia is only symmetrical as vertically both left and right of the

Building on the Cambodian flag is identical.

6)Nigeria: Nigeria is symmetrical both vertically and horizontally as it will be green and white left to right and green to white top to bottom.

The Switzerland flag has lines of symmetry because the flag is a square.The lines could go horizantaly diagonally and vertically there are 3 lines of symmetry.

The Czech Republic flag has no lines of symmetry because the shapes are not right and it doesn’t have a line vertically horizontally and diagonally.

The Cambodia flag has lines of symmetry.It can’t go horizontally because it has a star but it can go vertically and diagonally.The Vanuatu flag has no lines of symmetry because the shapes are not right and it does not have lines vertically horizontally diagonally.the Cambodia flag does have lines of symmetry because it has rectangles and rectangles do have lines of symmetry.

(Switzerland == The Switzerland flag has got 4 SYMMETRICAL lines because………. …. …..)

1= The 1st line is Horizontal.

2=The 2rd line is vertical.

3=The 3rd line is diagonal beggining from the left .

4=The 4 th line is diagonal beggining from the right .

(Czech Republic ===The Czech Republic has got 2 SYMMETRICAL lines and it is shown just below ……….)

1=The first line comes from the left and goes down diagonally

2=The second line comes from the right and goes down diagonally as well as the first one..

I know this because if I do one horizontal or vertical the pattern won’t be the same.

Somalia === Somalia has 4 SYMMETRICAL lines because ………

1st=Diagonally from left

2st=Diagonally from right

3st=Line for vertical

4st =line for horizontal

Vanuatu== Vanuatu has 2 symmetrical lines

One is horizontal one is vertical

I know this because if we did diagonally it would have not been right because of the pattern or else the pattern won’t be on any side.

Cambodia has only one symmetrical line and its vertical because the pattern is same and it’s in the middle.

Nigeria has 2 symmetrical lines because the size and pattern are same and the 2sides are vertical and other one is horizontal.

Switzerland has 4 lines of symmetry. I know this because it is the same on each side you can do it horizontaly verticaly and diangonaly.

Czsch Republic has 0 lines of symmetry . I know this because the colours are different and if you follow it verticaly and horizontaly it won’t be the same on each side.

Cambodia has 1 line of symmetry . I know this because if you do it verticaly it is

the same on each side and if you do it horizontaly and diagonally it isn’t the same on each side as symmetry means exactly the same on each side.

Somalia has 1 line of symmetry . I know this because if you do it verticaly it will be the exactly the same on each side and it won’t be exactly the same on each side if you do it horizontaly and diagonally.

Vanuatu has 0 lines of symmetry . I know this because if you do it verticaly you will have that big design on one side and not the other Also the colours are different so it won’t be symmetrical.

Nigeria has 2 lines of symmetry . I know this because if you do It verticaly it will be the same on each side and if you do it horizontaly it will also be the same on each side but if you do it diagonally it won’t be the same on each side as symmetrical means exactly the same on each side .

Switzerland has 4 lines of symmetry because it is the only square flag so you put a line horizontaly,verticaly and verticaly.

Czech Republic has 0 lines of symmetry because it has different colours meaning that if you put a line horizontaly it won’t be symmetrical because the top white and the bottom is red.

Somalia Has 1 line of symmetry which is down the middle because

1) The first flag has 4 line of symmetry, they are one vertically,one horizontally and two diagonal. Ikon because the Switzerland flag is the only square flag in the world so it has 4 lines of symmetry and same with the cross.

2) The second flag which is Czech Republic has zero sides of symmetry because the cours don’t match and have no lines of symmetry.

3) Somalia has one line of symmetry because it is a rectangle so it only has one

line of symmetry and it doesn’t matter about the star.

4)Vanuatu has 0 lines of symmetry because of the colour,patterns and the symbol is at the left and there isn’t one at the right so it can’t be symmetrical.

5) Cambodia has only one line of symmetry because firstly it is an rectangle and it can go through the castle once and that’s from the middle.

6) Nigeria has two lines of symmetry, one through the middle and one verticaly because the colours match so it can go through two ways middle and horizontal.

1 )The Swiss flag has 4 lines of symmetry. I know this because it is actually a squared shape flag so acting upon my previous knowledge squares have 2 diagonal lines starting from the corners and one horizontal and fertile line of symmetry.

2) Czech flag has zero lines of symmetry due to the multiple cities colours on it. For example if you’d put a mirror or line vertically in the middle the blue isn’t on either sides.

3) The Somalian flag only has one line of symmetry. This is because there’s a star in the middle pf the flag. The only probable solution would be to act it to a verticals line. If dong a horizontal line ; where a star has 5 cone shaped edges on it the bottom ones with lots not be identical 3-2.

4) The Vanuatu flag is rectangular yet it has zero lines of symmetry b cause of the differed colour coordination so the horizontal and vertical lines won’t be the same.

5) Next, the Cambodian flag has only one line of symmetry this is as if you’d put it in the middle the larger tower wold be a identical halved solution and also the other two.

6) Lastly, the Nigerian flag has 2 lines of symmetry as the colours are the same and the shape iss a rectangular shape. This means there’d be 2 lines one verticals and one horizontal.

1)The first flag has 4 lines of symmetry because you could fold it and then open it it will still look the same on both sides.

2)The second flay has 0 because if you fold it won’t be the same on both sides.

3)The third flay has 1 because if you fold it will be the same on both sides and there won’t be other on because it will not be symmetrical on both sides.

4)The fourth one has 0 because if you fold it it won’t be the same on both sides because then it won’t be symmetrical.

5)The fivthe one has 1line and if you fold it will still be the same on both sides.

6)The sixth one has 2 because if you fold it 2 times it will be the same on both sides.

Switzerland has 4 lines of symmetry because it’s a square and a line of symmetry is horizontally,one is vertically and two are from corner to other.

Czech Republic has 2 lines of symmetry because it’s a rectangle and one line is

horizontally and the other one is vertically.

Somalia only has one line of symmetry and that is vertically.

Vanuatu has only one line of symmetry and it’s horizontally.

Nigeria has 2 lines of symmetry and they’re both horizontally.

Cambodia has 2 lines of symmetry and they’re both

Switzerland has 4 lines of symmetry.

Czech Republic has 0 lines of symmetry because of the colours on the flag .

Somalia has 1 line of symmetry because of the star in the middle.

Vanuatu has 0 lines of symmetry because of the pattern.

Cambodia has 1 line of symmetry because of the building in the middle.

Nigeria has 2 lines of symmetry because it is a rectangle it can’t have 4 lines of symmetry.

Switzerland 🇨🇭 = 4 lines of symmetry

Czech Republic 🇨🇿 = 0 lines of symmetry

Somalia 🇸🇴 = 1 line of symmetry

Vanuatu 🇻🇺 = 0 line of symmetry

Cambodia 🇰🇭 = 1 line of symmetry

Nigeria 🇳🇬 = 2 line of symmetry

1) It has 4 lines of symmetry because if you do it vertically and horizontally you will have it the same on both sides.

2) It has o lines of symmetry because of the pattern.

3) It has 1 line of symmetry because you can only go vertically.

4) It has 0 lines of symmetry because of the patterns.

5) It has 1 line of symmetry because it can be split vertically.

6) It has 2 lines of symmetry one vertically and one horizontally.

Excellent questioning and probing ensuring children gained. Well done.
