I can calculate angle measures using the relationships of supplementary and complementary angles.

1
Complementary angles are two or more angles that add up to exactly 90 degrees.
2
Supplementary angles are two or more angles that add up to exactly 180 degrees, forming a straight line.
3
To find the complement of an angle, subtract the given angle from 90 degrees; to find the supplement, subtract from 180 degrees.
