![]() Now, we can outline the following basic properties of a linear pair of angles. In the same way, we can prove that each linear pair of angles is a pair of supplementary angles. By the definition of supplementary angles, angles 1 and 2 are supplementary angles. Now, place the protractor at that point, and its midpoint should touch the marked point O. ![]() Published by Houghton Mifflin Harcourt Publishing Company.

How to Construct an Angle (using protractor) Draw a ray OA of any length. The angle or arc that when added to a given angle or arc makes 180° or a semicircle. Here, AXD and CXD are supplementary angles. Therefore, we can conclude that the requirement of supplementary angles is ' the sum of angles must be 180 degrees'. For example, if x and y are supplementary angles then. This example is from Wikipedia and may be reused under a CC BY-SA license. The definition of supplementary angles is 'Two angles are supplementary angles if their sum is 180 degrees'. The exterior angle is the supplementary angle to the interior angle. These angles share these properties, making them unique angles and important ones to learn when working with applications and problems involving angles and algebra. Supplementary angles are two angles whose measures add up to 180°. Supplementary angles: Angles that add up to 180 (a straight angle) are called supplementary angles. Supplementary angles definition in english. Congruent supplementary angles are angles that meet two conditions - they are congruent and they are supplementary.
