Question

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 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 alternate 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. 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 interior angles, so their measures must be the same

Answer 1

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

This is because when a transversal crosses parallel lines, the corresponding angles formed are equal.
