Angle Relationships Test Practice

Given the following two parallel lines cut by a transversal. Which pair of angles represents alternate exterior angles?

Given the following two parallel lines that have been cut by a transversal. True or False, \angle6 and \angle4 are vertical angles?

• True

• False

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

This is what kind of angle?

• obtuse

• right

• straight

• acute

What is the value of <DBC?

• 17

• 70

• 79

• 83

Find the value of b.

Answer explanation

Set up an equation.

-2b+60 = 3b + 45

Add 2b on both sides

60 = 5b + 45

Isolate the variable and solve the two-step equation for a.

Find x.

Find the value of b.

Answer explanation

Set up an equation.

160 - 7b = 3b + 130

Add 7b on both sides

160 = 10b + 130

Solve the two-step equation. Isolate the variable by using inverse operations.

Subtract 130 on both sides.

Then divide both sides by 10

Find the measure of angle CBD.

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles
