If m∠1 = 50, then m∠5 =

1. angle 1 = 50 degrees [ Reason is Given]

2. angle 1 and angle 5 are corresponding angles [Given]

3 ... Therefore angle1=angle 5 [ Corresponding angles are = ]

4 ... Therefore angle 5 = 50 degrees [ = angles have same measure]

The above assumes that we are talking about corresponding angles of congruent or similar polygons or corresponding angles forme when a transversal intersects two parallel lines
