Question

Can someone check the answers for these geometry questions? Please? Thank you.

Answer 1

Looks good to me:)

Answer 2

I think that:
<5 and <18 are alternate Interior angles

Answer 3

I put that that they are congruent for number 1.

Answer 4

<2 and <18 are corresponding angles, furthermore also <18 and <10 are corresponding angles.
So <2 and <10 are corresponding angles by the transitive property

Answer 5

Aren't they supplementary because they're same-side interior angles if a and b are parallel?

Answer 6

Wait...I see...I'll fix it. Thank you!

Answer 7

also:
<4 and <14 are alternate Interior angles

Answer 8

That is only if line c and line d are parallel because they are dividing angles 4 and 14.
