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

Answer 1

The correct response is:

Angle 4 and angle 5 are alternate interior angles, so their measures must be the same.

This is because when a transversal intersects two parallel lines, the alternate interior angles formed are equal.
