Solution

The correct option is C Exterior Alternate angles
When a pair of parallel lines are cut by a transversal, alternate exterior angles are formed. Alternate exterior angles are a pair of angles on the outer side of each of the two parallel lines but on opposite sides of the transversal.
Hence, $∠ 1$ and $∠ 2$ are called Exterior Alternate angles.
