Question

If M and N are parallel and angle 4 is 122°%0D%0A122%0D%0A°%0D%0A , what is the measure of angle 5? How do you know?

Answer 1

If M and N are parallel, then angles 4 and 5 are corresponding angles. Corresponding angles are congruent when two parallel lines are intersected by a transversal. Therefore, the measure of angle 5 is also 122°.
