ANGLE RELATIONSHIP

​Step 1 : Identify the angle relationship between angle A and angle B.

Multiple Choice

What type of angles are shown?

• Complementary (90°)

• Supplementary (180°)

• Vertical (equal measure)

​
Step 2 : Set up the equation that will help you find the value of x.

Multiple Choice

Select the equation that will help you find the value of x.

• 5x + x = 90

• 5x + x = 180

• 5x = x

​Step 3: Solve the equation.

5x + x = 180
5x+ 1x= 180
6x = 180 ( divide both sides by 6)
x = 30

Multiple Choice

Angle 1 and Angle 3 are ?

• supplementary angles (180°)

• complementary angles (90°)

• vertical angles (equal)

Multiple Choice

Angle 1 and Angle 2 are ?

• supplementary angles (180°)

• complementary angles (90°)

• vertical angles (equal)

Multiple Choice

Angle 1 and Angle 4 are ?

• supplementary angles (180°)

• complementary angles (90°)

• vertical angles (equal)

Multiple Choice

Angle 2 and Angle 4 are ?

• supplementary angles (180°)

• complementary angles (90°)

• vertical angles (equal)

​​Step 1 : Identify the angle relationship between angle A and angle B.

Multiple Choice

What type of angle relationship is shown?

• Complementary (90°)

• Supplementary (180°)

• Vertical ( equal measure)

​​Step 2: Set up the equation that will help you find the value of x.

Multiple Choice

Select the equation that will help you find the value of x.

• 50 + 2x = 90

• 50 + 2x = 180

• 50= 2x

​​Step 3: Solve the equation.
50 + 2x = 90 subtract 50 to both sides
2x = 40 divide both sides by 2
x = 20

Multiple Choice

Name a pair of adjacent angles.

• ∠LON and ∠MOP
  

• ∠MON and ∠NOP
  

• ∠LOM  and ∠NOP
  

• ∠LOM AND ∠LON

​Step 1 : Angle b and 53° are what type of angles ?

Multiple Choice

Angle b and 53° are ?

• Complementary angles (90°)

• Supplementary angles (180°)

• Vertical angles ( equal)

​Step 2 : Set up the equation that will help you find the value of x.

Multiple Choice

Select the equation that will help you find the value of b.

• b + 53 = 90

• b + 53 = 180

• b = 53

​Step 3 : Solve the equation.
b + 53 = 90 subtract 53 to both sides
b = 37

Multiple Choice

Find the supplementary angle to an angle that is 74.5°.

• 15.5

• 105.5

​Step 1 :
Identify the type of relationship the angles have.

Multiple Choice

The angle relationship shown is ?

• Complementary (90°)

• Supplementary (180°)

• Vertical ( equal measure)

​Step 2 :
Set up the equation that will help you find the value of x.

Multiple Choice

Select the equation that will help you find the value of x.

• 156 + 9x+30=90

• 156+9x+30=180

• 9x+30=156

​Step 3 :
Solve the equation
9x+30=156 subtract 30 to both sides
9x = 126 divide both sides by 9
x = 14
