Theorem 2-7-3- If two congruent angles are supplementary, then each angle is a right angle. (This is the four-angle version.). The previous four theorems about complementary and supplementary angles come in pairs: One of the theorems involves three segments or angles, and the other, which is based on the same idea, involves four segments or angles. So we set x = y: y + y = 180 To solve for y, we type this equation into our search engine and we get: The supplement of an acute angle is acute. Supplementary Angles Theorem. Game plans are especially helpful for longer proofs, because without a plan, you might get lost in the middle of the proof. Not always. In other words, when complementary angles are put together, they form a right angle (90 degrees). Reason for statement 5: If two angles are complementary to two other congruent angles, then they’re congruent. If two angles are supplementary to the same angle (or to congruent angles), then they are congruent. If two angles are supplementary to the same angle (or to congruent angles), then they are congruent. 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. Rating.
