Is there such a thing as Positive Criticism? Complementary angles are two angles that add up to 90°, or a right angle; two supplementary angles add up to 180°, or a straight angle. Because ∠1 and ∠2 are supplementary and ∠3 and ∠4 are supplementary, m∠1 + m∠2 = 180° and m∠3 + m∠4 = by the defi nition of supplementary angles. That should be enough to complete the proof.
