If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular. Exterior and interior angles add up to 180 degrees. Therefore, if the exterior angle is perpendicular, then the interior angle must also be perpendicular in order to sum up to 180 degrees.
