The Testbook platform offers weekly tests preparation, live classes, and exam series. What is the definition of a complementary angle Two angles that have the same measure. This is the only sharp angle marked.ĭo you want to score well in your Maths exams? Then, you are at the right place. \( \angle 1 \) is an obtuse angle, therefore any one acute angle combined with any obtuse angle is a supplementary angle. Supplementary angles and complementary angles are defined with respect to the addition of two angles. The supplementary angle to \( \angle 1 \) is \( \angle 6 \) Which of the following highlighted angles is supplementary to \( \angle 1 \) ? This means that whenever you see the word supplement, you can replace it with the mathematical expression (180 - A). Definition of supplementary angle how to#In other words, if, \( Angle 1 Angle 2 = \angle 180^ \)Įxample : 4 Two parallel lines are cut by a transversal in the illustration below. This tutorial introduces you to supplementary angles and shows you how to use them to solve for a missing angle measurement. When supplementary angles are combined, they make a straight angle (180 degrees). When two lines intersect each other we get 4 pairs of supplementary angles. The term “supplementary angles” refers to a pair of angles that always add up to 180°. In the example shown, 125 and 55 add up to give 180, so they are called supplementary angles. Definition of supplementary angle full#Angles in geometry include acute angles, obtuse angles, right angles, reflex angles, and straight angles.In this article, we will learn supplementary angles in full detail, including their types, properties, and so on.
