In this section we will… Look at different kinds of angle pairs Complementary Supplementary Adjacent Linear Vertical Apply angle pair relationship in algebra

What is adjacent again? When two angles share a common side, they are considered adjacent.

What is the difference between complementary & supplementary? Complementary: angles that add up to ninety degrees. Supplementary: angles that add up to one hundred eighty degrees.

Angle Pairs Example 1: Look at the following diagram and find the following: A pair of complementary angles A pair of supplementary angles A pair of adjacent angles A pair of vertical angles S R 25 65 P 65 115 T Q V

Finding the complement and supplement

Finding the complement and supplement

What is a linear pair? A linear pair is a supplementary adjacent angle.

What are vertical angles? Vertical angles are created by two intersecting lines and are across from each other. They are congruent angles.
