Which statement regarding the interior and exterior angles of a triangle is 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 the remote interior angle.
An interior angle is an angle inside a shape. Since triangles have three angles, they have three interior angles. In this triangle, angles A, B and C are all interior angles. Just as the pieces in a jigsaw puzzle fit together perfectly, the interior angles in a triangle must fit with each other. The sum of the interior angles is always 180 degrees. In other words, a + b + c = 180 degrees.
