NOTES
Supplementary Angles Two angles are called
supplementary angles if the sum of their degree
measurements equals 180 degrees. One of the
supplementary angles is said to be the supplement
of the other. Complementary Angles Two angles
are called complementary angles if the sum of
their degree measurements equals 90 degrees. One
of the complementary angles is said to be the
complement of the other.
