Angle Basics and Angle Relationships

• 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

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

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

What is the measure of <DBC? (just type the number)

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

Solve for x.
