Looks good to me:)

michele_laino · Answer

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

anonymous · Answer

I put that that they are congruent for number 1.

michele_laino · Answer

<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

anonymous · Answer

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

anonymous · Answer

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

michele_laino · Answer

also:
<4 and <14 are alternate Interior angles

anonymous · Answer

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