which statement regarding the interior and exterior angles of a triangle is always true? an exterior angle is supplementary to the adjacent interior angle. an adjacent interior angle is supplementary to a remote interior angle. a remote interior angle is congruent to the exterior angle. an exterior angle is supplementary to a remote interior angle.

Answer

Explanation:

Step1: Recall angle - relationship definitions

By definition, an exterior angle of a triangle and its adjacent interior angle form a linear - pair.

Step2: Understand linear - pair properties

A linear - pair of angles is supplementary, meaning the sum of the measures of the two angles is 180°.

Answer:

An exterior angle is supplementary to the adjacent interior angle.
