Thm 2-3 – Congruent Complements Theorem If two angles are complements of the same angle ( or of congruent angles), then the two angles are congruent. Theorems 2-4 and 2-5 All right angles are congruent. If two angles are congruent and supplementary, then each is a right angle. Joke Time Why do bees have sticky hair? Because they have honeycombs.
