If angle 4 is 42° and lines M and N are parallel, give a reason why angle 5 is also 42°. (1 point) Responses Angle 4 and angle 5 are corresponding angles, so their measures are congruent. Angle 4 and angle 5 are corresponding 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 vertical angles, so their measures are congruent. Angle 4 and angle 5 are interior angles, so their measures must be the same. Angle 4 and angle 5 are interior angles, so their measures must be the same. Angle 4 and angle 5 are alternate interior angles, so their measures must be the same.

Answer 1

If lines M and N are parallel and angle 4 measures 42°, then the reason that angle 5 is also 42° is that angle 4 and angle 5 are corresponding angles, so their measures are congruent.

This is because corresponding angles are pairs of angles that are in the same position on different parallel lines when a transversal crosses them.
