How does the Complementary and Supplementary Angles Calculator work?

This calculator determines the complementary and supplementary angle of a given angle that you enter OR it checks to see if two angles that you enter are complementary or supplementary.
This calculator has 3 inputs.

What 2 formulas are used for the Complementary and Supplementary Angles Calculator?

  1. IF an angle is less than 90°, then the complementary angle is 90 - θ
  2. IF an angle is less than 1800°, then the supplementary angle is 180 - θ
