Angle Relationships

Angle Relationships

Before we get started...

• Grab your notebook. You're going to want to take notes!

• Open up your Module 5 Vocabulary assignment. While you work through this lesson, work on your vocabulary assignment.

• Read each slide carefully.

• Try your best on ALL questions.

• Repeat the lesson as many times as you need to master the material!

These next two slides are all vocabulary!

TAKE NOTES. You will need them for the rest of the Quizizz.

Let's add some algebra now!

Using your knowledge of angle relationships, answer the following questions.

Multiple Choice

Find the m∠1

• 67

• 113

• 180

• 23

Multiple Choice

Tell whether the angles are complementary or supplementary. Then find the value of x.

• Complementary; x=25
• Complementary; x=5
• Supplementary; x=25
• Supplementary; x=5

Multiple Choice

An angle has a measure of 72^o. What is the measure of its complement?

• ^8o

• 18^o

• 108^o

• ^90o

Multiple Choice

Which equation could you use to solve for the value of x?

• 3x + 10 − 2x = 180

• 3x + 10 = 180

• 3x + 10 + 2x = 180

• 3x + 10 = 2x

Multiple Choice

• 2x-6=7x+4
• 2x-6+7x+4=90
• 2x-6+7x+4=180
• 2x-6+7x+4=360

Multiple Choice

If ∠COB is 124°, then what is ∠BOD? How are they related?

• 56°, they are supplementary

• 56°, they are complementary

• 124°, they are vertical

• 124º, they are corresponding

Multiple Choice
