Supplementary angles are two angles whose sum is equal to 180 degrees. This means that when we add the measures of the two angles together, the result is 180 degrees.
For example, if one angle measures 90 degrees, its supplementary angle would measure 90 degrees as well in order for the sum to be 180 degrees. Similarly, if one angle measures 120 degrees, its supplementary angle would measure 60 degrees to make their sum equal to 180 degrees.
