If one angle is known, its complementary angle can be found by subtracting the measure of its angle from 90 o.. ⁰, then those two angles are called as supplementary angles. Supplementary Angles When the sum of two angles is 180°, then the angles are known as supplementary angles. Supplementary angles do not need to be adjacent angles (angles next to one another). Because x and 2x are complementary angles, we have. Let x and y be the two angles which are complementary. The following angles are also supplementary since the sum of the measures equal 180 degrees. Even if the sum of three angles is 180 degrees, they are NOT considered supplementary. Although the angle measurement of straight is equal to 180 degrees, a straight angle can’t be called a supplementary angle because, the angle only appears in a single form. Being that we have to draw two supplementary angles, it is essential to know that the sum of these angles is 180 degrees. If sum of two angles is 180°, they are supplementary.For example60° + 120° = 180°Since, sum of both angles is 180°So, they are supplementaryAre these anglessupplementary?68° + 132° = 200°≠ 180°Since, sum of both the angles is not 180°So, they arenot supplementaryAre these angles supplementary?100° + Clearly, 30° is the complement of 60° and 60° is the complement of 30°.
