# Investigation 3: Complements/Supplements/Linear Pairs/Straight Angles

Topic:
Angles
Define complementary angles, supplementary angles, linear pair angles, and straight angles.
In this exercise you will investigate the special angle relationships: complementary, supplementary, linear pairs, and straight angles. Directions: Answer the following questions in the space provided. When you decide on an answer as a group, add it to the Breakout Room slides.

1. Click only on the box that says Complementary Angles. 1a) What is true about the sum (what they add up to) of complementary angles?

1b) Give 3 examples of angles that are complementary and find their sum.

1c) Create a definition for complementary angles.

2. Click only on the box that says Supplementary Angles. 2a) What is true about the sum (what they add up to) of supplementary angles?

2b) Give 3 examples of angles that are supplementary and find their sum.

2c) Create a definition for supplementary angles.

3. Click only on the box that says Linear Pair Angles. 3a) What is true about the sum (what they add up to) of angles that form linear pairs?

3b) Give 3 examples of angles that form linear pairs and find their sum.

3c) Create a definition for linear pairs.

4. Click only on the box that says Straight Angle. 4a) What is true about the angle measurement of a straight angle?

4b) Give an example of a straight angle and it's degree measure.

4c) Create a definition for a straight angle.

In this exercise you will investigate the relationship between angles that are complementary, supplementary, linear pairs and straight angles.
