Complimentary angles are two angles whose sum is equal to 90 degrees. Supplementary angles are two angles whose sum is equal to 180 degrees. These angles can be used to solve for missing angles in a triangle.

Complimentary angles can be used to create a right angle, which is the same as a 90 degree angle. Supplementary angles add up to 180 degrees, which is the same as a straight line. You can draw a line from any point on a circle and make two complementary angles.
