Apr 18, 2016 · (180 – adjacent interior angle = sum of the two interior angles) Likewise, the difference between 180 and the adjacent interior angle is equal to the exterior angle (because they form a straight line). (180 – adjacent interior angle = exterior angle) Therefore, the two opposite interior angles and the exterior angle must be equal. So to ... Exterior and Interior Angles of Triangle.
