Question

What is the answer to this problem?

Answer 1

Answer:

B.) Transitive Property of Congruency; If parallel lines have a transversal, then alternative interior angles are congruent.

Step-by-step explanation:

Alternate interior angles are the two angles that are inbetween the parallel lines but are on opposite sides of the transversal.  Angles 4 and 5 are alternate interior, and therefore, they are congruent.
