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

What property do vertical angles share?

• They are always supplementary

• They share a common vertex but are not equal

• They are congruent

• They are always complementary

Which angles are formed by intersecting lines?

• Adjacent angles

• Supplementary angles

• Vertical angles

• Complementary angles

If one angle is 70 degrees, what is its vertical angle?

• 180 degrees

• 70 degrees

• 110 degrees

• 20 degrees

How can complementary angles be identified?

• Their sum is 180 degrees

• They form a straight angle

• They are adjacent to each other

• Their sum is 90 degrees

How can you remember the sum of complementary angles?

• Turn the 'S' into an 8

• Turn the 'C' into a 9

• Associate it with a right angle

• Remember it as half of 180

What is the sum of supplementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

What is true about the angles that form a straight angle?

• They are supplementary

• They are vertical angles

• They are adjacent angles

• They are complementary

Which angles do not necessarily have to be adjacent?

• Both complementary and supplementary angles

• Supplementary angles

• Complementary angles

• Vertical angles

If angle one is 100 degrees in a supplementary pair, what is angle two?

• 70 degrees

• 90 degrees

• 100 degrees

• 80 degrees
