Complementary angles are a pair of angles that, when added together, equal 90°. In simpler terms, if you have ∠1 and ∠2, and their measures sum up to 90°, then ∠1 and ∠2 are considered complementary. We refer to ∠1 and ∠2 as each other's complements based on this relationship.
In geometry, complementary angles are defined as two angles whose sum is 90 degrees. Two complementary angles when put together form a right angle. Learn the differences between complementary and supplementary angles.
Complementary angles : Two angles are complementary, if the sum of their measures is equal to 90. Supplementary angles : Two angles are supplementary angles if the sum of their measures is equal to 180 degrees. Problem 1 : Angles A and B are complementary.
Problems on complementary and supplementary angles are most easy to solve if you just remember the numbers 90 and 180. With the definitions given below, you will know how these numbers have been used in angles. You have ample problems to identify and calculate the missing measure of angles.

Congruent Complements Theorem. If two angles are complements of the same angle (or of congruent angles), then the two angles are congruent. Congruent Supplements Theorem. If two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent. Right Angles Theorem. All right angles are congruent.
