Name a pair supplementary angles
http://www.mathsisfun.com/geometry/supplementary-angles.html
To find a pair of supplementary angles, we need to look for two angles whose measures add up to 180 degrees. Here is an example:
Let's say we have Angle A and Angle B. Angle A measures 120 degrees. To find a supplementary angle to Angle A, we subtract its measure from 180 degrees.
180 degrees - 120 degrees = 60 degrees
Therefore, Angle B measures 60 degrees. Angle A (120 degrees) and Angle B (60 degrees) form a pair of supplementary angles because their measures add up to 180 degrees.
