Exactly what it says in the title, today we are moving on to applying our knowledge of angles to identify missing angle sizes.**Three words you need to understand today: Vertical….Opposite…. Angles**

Gold:

5. a) 133 degrees

5. b) 73 degrees

5. c) 52 degrees

5. d) 16 degrees

5. e) 81 degrees

5. f) 23 degrees

6) a=20 b= 20×3=60

7) g=111 degrees f=28 degrees

111+139+28=278

360-278=82

82/2=41

angle x and y are vertically opposite.

8)right angle= 90 degrees

30 degrees

e=60 degrees

g=60 degrees

f=120 to check our work we add all of our angles together to 360 so our prediction is correct.

90+30+60+120+60=360

Gold:

a)133°

b)141°

c)52°

d)16°

e)81°

f)23°

I disagree with Amir because G is 60 ° not 30°. This is because, there is a angle which is 90, 30, 60 and 120 degrees.

Calculation: 90 + 30 + 60 + 120 = 300

Therefore the missing angle must be 60°.

Calculation: 360 – 300 = 60

Calculation: 120 + 90 + 60 + 60 + 30 = 360° (a full turn)

Hi Maria, you have completed question 5 but not 6 or 7.

5b is incorrect, all others are correct. Please complete the task set.

b) 73°

6) a- 20 b- 60 ?

7) No, y and x are not vertically opposite. If it was 139° it would be vertically opposite. However, because G is 112° this does not mean they are vertically opposite.

Glad to see you working on the blog Maria.

Gold

1.133degrees

2.73degrees

3.52degrees

4.16degrees

5.81degrees

6. Don’t know how to work out

6.dont know

6) a and b need to total the same angle as vertically opposite which is 80degrees.

Your work seems incomplete where is 7 and Amirs reasoning question?

Gold

6.dont know

You have the ones you have completed right. Please complete the rest .

5)Work out the unknown angles.

a)a=133°

b)b=73°

c)c=52°

d)d=16°

e)e=81°

f)f=23°

6)Angle b is 3 times the size of angle a

a+3b=80°

80÷4=20°

a=20°

20×3=60°

b=60°

7)Angle f is one quarter of the size of angle g

Angle f is 28°

The angles are vertically opposite because the angles opposite each other when two lines cross are always equal. In this question the angles are vertically opposite.

Well done, great work Hadisa. Have a look at your working out for the last question.

All correct but no.7, angle x and y are not vertically opposite angles.

5)Angle a=133degrees

I don’t understand how to solve b

Angle c=52degrees

Angle D=16degrees

Angle e=81degrees

Angle f=23degrees

6)a=20degrees b=60degrees

7)Angle x and y are not vertically opposite as angle g is 112degrees not 139degrees(which is the bottom angle).

Really good work Abdulwahab. To solve be, what do you know about vertically opposite angles?

5b) is still a vertically opposite angle.

All correct, please complete the task by completing Amir’s reasoning question. Thank you

Silver:

3)

A)y=29

B)z=123

4)

A)Annie is correct, when both of the angles are vertex they are equal.

Jessica, you did the same thing yesterday. I worry you’re unable to follow very simple instructions on the blog. Jessica is in MRS AHMED’S maths group…. this group is doing the BRONZE challenge.

There’s a reason you can’t access the silver, follow the instructions you have been given repeatedly please.

1a)130 degrees

2a)50 degrees

3a)130 degrees

4a)50 degrees

B)a+b=180 degrees

They are adjacent angles they will always add up to 180 degrees

c+d=180 degrees

c)a and c-they are the same 130 degrees .

D)b and d-they are the same 50 degrees

E) Vertically opposite angles equal the same amount of degrees

A correct

B correct

C incorrect

D correct

E incorrect

B

Hi Sofia, I don’t understand what you’ve done.

You’re completing the bronze challenge with only 2 questions. Where have you got 3a and 4a-e?

Well done Sofia these are all correct.

i also dont have a protractor

You don’t need a protractor Haya!

How many degrees in a right angle?

How many degrees on a straight line?

How many degrees around a point?

bronze

miss Ahmed the first question is already hard for me.

and the second question

Answer Mrs Jones questions Haya, you haven’t watched the video throughly enough. Look at the poster it explains how to vertically opposite angles have the same measurement.

3a) 29 degrees because I saw the other 29 and they were the same size saw was the top and bottom.

3b) 132 degrees because as you can see there the angles are equivalent/the same so 48 x 2 is 96 plus 132 is 228,360 take away 228 is 132.

4) Anie is wrong because not every vertical angles are equivalent in size, also you can tell they are not the same just by looking at it.

5a) 133 degrees

5b) 52 degrees

5c) 73 degrees

5d) 16 degrees

Good morning Aliko, well done with your maths today. It is alright however you need to be more specific and clearer with your explanations. Keep up the good work.

Silver:

3)

a.y=29

b.z=132

4)

a. Annie is correct because when both of the opposite angles share the same Vertex it means they are equal to each other

Good morning Anora, question 3 is correct however you have not completed the sentences on how you know this. Please have another go at question 4 and complete question 5 please.
