Identify the angle pair.

• complementary angles

• linear pair

• supplementary 

• vertical angles

What angle is adjacent and supplementary to angle 5?

• ∠4

• ∠1

• ∠3

• ∠2

Which equation will help you solve for x?

Angles A and B are COMPLEMENTARY. Angle A has a measure of 30 degrees, what is the angle measure of angle B?

• 30 degrees

• 60 degrees

• 90 degrees

• 180 degrees

Angles C and D are SUPPLEMENTARY. Angle C has a measure of 30 degrees, what is the angle measure of angle D?

• 30 degrees

• 60 degrees

• 150 degrees

• 180 degrees

What is the equation that could be used to solve for the missing angle measure?

• x + 146 = 180

• x + 146 = 90

• x = 146

• 146 - x = 90

Which equation below would you use to solve for x?

• 5x + x + 30 = 180

• 5x + x + 30 = 90

• 5x = x + 30

• 5x + 180 = x + 30

• 5x = x + 30 + 180
