<center>Complementary or Supplementary Angles</center>
Two angles are complementary if the sum of their angles equals 90o.
If one angle is known, its complementary angle can be found by subtracting the measure of its angle from 90o.Example: What is the complementary angle of 43o?
Solution: 90o - 43o = 47oTwo angles are supplementary if the sum of their angles equals 180o.
If one angle is known, its supplementary angle can be found by subtracting the measure of its angle from 180o.Example: What is the supplementary angle of 143o?
Solution: 180o - 143o = 37o
