In the figure, Angle 1 is congruent to Angle 2. What reason can be used to prove that m is parallel to n?

• If a pair of vertical angles is congruent, then the lines forming them are parallel.

• If a pair of angles formed by a transversal is corresponding and supplementary, then the two lines are parallel.

• If a pair of angles is congruent and the sum of their measures is 180º, then the lines forming the angles are parallel.

• If two lines are intersected by a transversal, and a pair of corresponding angles is congruent, then the two lines are parallel.
