Angle Relationships and Solving for Unknown Measures

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles

Supplementary angles always add up to

Which angle is a vertical angle to with \angle7 ?

Find x.

• 0.3

• 1

• 9

What is the value of x?

Which equation would you use to find x?

• 12x - 8 + 136 = 4x

• 12x - 8 + 4x = 136

• 4x + 136 = 12x - 8

Identify the angle relationship and solve for x.

• x = 25

• x = 45

• x = 13

• x = 90

Which equation would you use to find x?

• 5x + 3 + 3 + 15x = 70

• 70 + 3 + 15x = 5 + 3

• 70 + 5x + 3 = 3 + 15x

• 5

• 35

• 25
