Exploring Angle Pair Relationships

This video tutorial covers four types of angle pair relationships: adjacent, vertical, complementary, and supplementary angles. It explains how adjacent angles share a common side, vertical angles are congruent, complementary angles sum to 90 degrees, and supplementary angles sum to 180 degrees. The tutorial also provides tips for remembering these relationships and includes practice problems to solve for missing angles.

What defines adjacent angles?

• Angles that have a sum of 180 degrees

• Angles that have a sum of 90 degrees

• Angles that share a common side

• Angles that are opposite to each other
