Parallel Lines Cut by a Transversal

Front

What is the relationship between vertical angles when two lines intersect?

Back

Vertical angles are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

Alternate interior angles are congruent.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.
