The interior angles of a four-sided object always at to 360 degrees. Therefore, if you know the other three angles, the solution to the fourth angle is: Angle4 = 360 - (Angle1 + Angle2 + Angle3) or... Angle4 = 360 - Angle1 - Angle2 - Angle3

### Can someone help you learn how to find the measures for complements or supplements and vice versa?

Complementary angles: Two angles that add up to a right angle (90&Acirc;&deg;). Each angle is complement of the other.For example, the complement of a 30&Acirc;&deg; is 60&Acirc;&deg; (90&Acirc;&deg; - 30&Acirc;&deg;).Supplementary angles: Two angles that add up to two right angles (180&Acirc;&deg;). Each angle is supplement of the other.For example, the supplement of a 30&Acirc;&deg; is 150&Acirc;&deg; (180&Acirc;&deg; - 30&Acirc;&deg;).
