Need answer

[noble stirrup]

Ok

[night pewter]

Hello

[noble stirrup]

Have you learned of vertical angles?

[night pewter]

Idk too much

[noble stirrup]

Ok then

What do angles in a straight line add up till?

[night pewter]

180?

[noble stirrup]

Yes

Let’s call the angle to the right of the 124 angle x

[night pewter]

So i need to 180-124?

[noble stirrup]

To get angle x

Yes

[night pewter]

@noble stirrup ok

[noble stirrup]

124 + x = 180

So x = 180 - 124

Which is?

[night pewter]

56

[noble stirrup]

Ok

Now 56 + a = 180

So a is ?

[night pewter]

124

[noble stirrup]

Yes

[night pewter]

And b

Is 56?

[noble stirrup]

No

[night pewter]

Oh

[noble stirrup]

As you see when there are two parallel lines

The corresponding angles of position are equal

For example in this

[night pewter]

So b is 124?

[noble stirrup]

Both these angles are in the bottom right quadrant of the two lines that split

Yes

[night pewter]

Also

Ohh ok i got it

So a= 56 and b= 124

@noble stirrup

[noble stirrup]

Look below that

B is the same as A

[night pewter]

So both are 124?

[noble stirrup]

Yes
