Angle 4 and angle 5 are vertical angles, so their measures are congruent.
Angle 4 and angle 5 are vertical angles, so their measures are congruent.

Angle 4 and angle 5 are corresponding angles, so their measures are congruent.

Answer 1

The correct response is:

**Angle 4 and angle 5 are corresponding angles, so their measures are congruent.**

This is because when two parallel lines are crossed by a transversal, the corresponding angles formed are congruent.
