All rights reserved. Supplementary angles are two angles that have a sum of 180°. If they are adjacent they will form a right angle. (Diagram: Heading – Nonadjacent Supplementary Angles, File name: Nonadjacent Supplementary Angles). What is the measure of a complementary angle? Hence when two supplementary angles are put together they form a ‘straight’ angle. B) State whether the given pairs are complementary or supplementary. Since one angle is 90°, the sum of the other two angles forms 90°. If the sum of two angles is 180⁰, then those two angles are called as supplementary angles. Complementary and Supplementary Angles The geometry worksheets on this page can be used to introduce and review the concepts of complementary and supplementary angles. If one of the angles is double the other angle, find the two angles. Equate the sum of these measures with 90° or 180° and solve for the value of x. Complementary and supplementary angles (no visual) Our mission is to provide a free, world-class education to anyone, anywhere. Definitions: Complementary angles are two angles with a sum of 90º. If x and y are supplementary angles and x = 88°. Similar to complementary angles, the two angles do not need to be adjacent. The word ‘supplementary’ came from the Latin word ‘supplere’ meaning ‘supply’. When a rectangular piece of bread is divided into two pieces by cutting along the diagonal, we get two right triangles, each with a pair of complementary angles. Two angles are complementary. Let x be the measure of the required supplementary angle. Example : 120° and 60° are supplementary angles. From the picture above, it is clear that the angles (x+1), (x-1) and (x+3) are complementary. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. If one angle is known, its complementary angle can be found by subtracting the measure of its angle from 90o. Each angle in the pair is said to be the supplement of the other. Diagram (Heading – Complementary and Supplementary Angles, File name – Complementary and Supplementary Angles) (Show 44°, 46° for complementary angle) From the picture above, it is clear that (2x+3) and (x-6) are supplementary angles.
