if angle 4 is 42 degrees and lines M and N are parallel, give a reason why angle 5 is also 42 degrees.

Question

a. angle 4 and angle 5 are interior angles, so their measure must be the same.
b. angle 4 and angle 5 are corresponding angles, so their measures are congruent.
c. Angle 4 and angle 5 are vertical angles, so their measures are congruent.
d. angle 4 and angle 5 are alternate interior angles, so their measures must be the same

Answer 1

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