I'd suggest you eliminate the least likely 1 or 2 answers, and then look up on the 'Net the other 2 or 3

mathaphobia · Answer

I mean for the first one does it prove that the vertical angles are congruent?

mathaphobia · Answer

How do I tell?

mathaphobia · Answer

I would assume so because of the measure of the angles am i correct?

mathmale · Answer

First, please obtain a definition of each "vertical angle theorem" and "corresponding angles theorem."  Most sites will provide you with illustrations and samples along with the definiitions.

mathaphobia · Answer

Vertical angles are always congruent.

mathaphobia · Answer

But wait I remember that vertical angles are like a x right?
