What are Complementary and Supplementary Angles in Geometry? - [5]

Two angles are complementary if they add to 90 degrees. Two angles are supplementary if they add to 180 degrees. Here we will solve several problems that involve diagrams that have either a complementary pair or supplementary pair of angles. We will have to solve for the unknown angle by using these facts. We will also explore the related ideas of vertical angles and adjacent angles.
