Lesson 1.5

Describe Angle Pair Relationships

Objectives
• Use special angle relationships to find angle measurements
Standard
• Prep for 13.0 – Students prove relationships between angles in polygons by using properties of complementary, supplementary, vertical and exterior angles.
• Complementary Angles
• Supplementary Angles
• Linear Pair
• Vertical Angles
Complementary Angles
• Two angles with the sum of their measures equaling 90°
Supplementary Angles
• Two angles with the sum of their measures equaling 180°
