Draw a triangle on your paper and to broaden the base of the triangle, so that it extends beyond the base of the angle. The base of the interior angle of a triangle is the interior angle and the exterior of the triangle between the extended line and outside of the interior angles is the exterior angle. A straight line has a measure of 180 degrees. That means that the interior angle + exterior angle = 180. So they are supplementary by definition of supplementary angles. A is the only option to which it is applied.
