Amber

9:31

I think i'm good at angles because my dad has been helping!

Mr Warbrick

9:32

Glad to hear Amber! You've made a good start to this morning's tasks :)

Kacie

9:32

Morning everyone!

Mr Warbrick

9:32

Morning Kacie!

Lewis S

9:32

Can I have help on 25 please?

Mr Warbrick

9:33

Of course!

What is every angle in an equilateral triangle?

Lewis S

9:33

Mr Warbrick

9:33

Not quite, try again

Lewis S

9:33

no 60

Mr Warbrick

9:33

Good

9:34

So, if you were to join three corners (or vertexs) together, you would have 3 x 60 = ?

Lewis S

9:34

180

Mr Warbrick

9:34

Right! Which is the same as angles where?

Lewis S

9:34

yes straight line = 180

Mr Warbrick

9:34

Good!

Chelsea

9:37

I need help with 27

Mr Warbrick

9:38

Okay, this is slightly tricky Chelsea

9:39

How big are the angles I've drawn in if the shape is equilateral?

9:43

Chelsea?

Amelia

9:44

I'm stuck on Q30 L1

Mr Warbrick

9:44

Okay, there will be a little bit of trial and error here!

Start by working out what a + b =

9:45

Which will be 360 - 243...

Chelsea

9:45

Wait i think i got it is a 36

Mr Warbrick

9:45

Yes, well done!

Amelia

9:46

117

Mr Warbrick

9:46

Good, now you need to play around a little with the numbers, till you found to numbers which add to 117 - where one is double the other

Mr Warbrick

9:47

For example, it could be 80 + 37 but that doesn't fit the double rule

Lewis S

9:47

done

Mr Warbrick

9:47

Well done Lewis :)

You're the first today

Amelia

9:50

I've tried 57, 58 and 59 but they all go around 117 because they're all even numbers and 117 isn't even

Mr Warbrick

9:51

Only one of the numbers needs to be even remember Amelia. Odd + Even = Odd

Mr Warbrick

9:51

So, one of 'a' or 'b' has to be even

Miss D

9:51

You guys have gone as quiet as my class!

Amelia 😊

9:53

59 and 58?

Mr Warbrick

9:53

So if 'b' was 58 to use your example, then 'a' would be 29 (half of that)

9:54

But they add up to 87, so it's not that, so those angles aren't big enough

Remember, a is half of b, not one less than
