Are same side exterior angles always congruent? Why?

Same side exterior angles are sometimes congruent. Rather, they are supplementary (i.e., add up to $$180º ), so they are only congruent when they are both $$90º . However, in the picture shown here the angles are not congruent, for no combinations of rigid motions would map one angle perfectly on top of the other.

Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles. The theorem states that same-side exterior angles are supplementary, meaning that they have a sum of 180 degrees.

yes because they are supplementary
