How do exterior angles relate to interior angles in a triangle?(1 point) Responses Exterior angles are always congruent to their associated interior angle. Exterior angles are always congruent to their associated interior angle. Exterior angle measures are always greater than the measure of their associated interior angle. Exterior angle measures are always greater than the measure of their associated interior angle. Exterior angles are always complementary to their associated interior angle. Exterior angles are always complementary to their associated interior angle. Exterior angles are always supplementary to their associated interior angle. Exterior angles are always supplementary to their associated interior angle.

The correct response is: Exterior angles are always supplementary to their associated interior angle.
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles, and the exterior angle and the adjacent interior angle together add up to 180 degrees, which makes them supplementary.
