Explanation:

Step1: Understand alternate exterior angles

Alternate exterior angles are formed when a transversal crosses two parallel lines. Angle 1 & Angle 7, Angle 2 & Angle 8 are alternate exterior angles.

Step2: Check congruency and supplementary property

By the alternate exterior angles theorem, if the two lines are parallel, alternate exterior angles are congruent. But there is no information given that the two lines are parallel here. So, they are not necessarily congruent. Also, supplementary angles add up to \(180^{\circ}\). Just being alternate exterior angles (without the parallel - line condition) does not make them supplementary.
