Complementary angles are angles that add up to give 90 degrees.
As shown in the figure above, the sum of the measure of angle a and angle b will be equal to 90 degrees.
So, angle a and b are complementary angles.
Supplementary angles are angles that add up to give 180 degrees.
As shown in the figure above, the sum of the measure of angle r and angle s will be equal to 180 degrees.
So, angle r and angle s are supplementary angles.
