ANGLE PAIRS PPTX

1. Describe Angle Pair Relationships

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

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

4. 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.

5. 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 65 115 25 65 P T S V Q R

7. Finding the complement and supplement

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

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