Alternate exterior angles

Explanation:

Alternate exterior angles are angles that are formed outside two parallel lines that cuts through a transversal line. these angles are formed on the opposite side of the transversal line ( alternate side).

Also Alternate exterior angles are congruent in nature are they are not adjacent angles as well
