Showing Equations That Are Parallel Lines Cut by a Transversal

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

In the diagram below, lines X and Y are parallel and cut by a transversal. The measure of ∠4 is 115°. Which argument explains why the measure of ∠6 is also 115°?

• ∠4 and ∠6 are exterior angles.

• ∠4 and ∠6 are alternate interior angles.

• ∠4 and ∠6 are vertical angles.

• ∠4 and ∠6 are corresponding angles.

What is the correct EQUATION to find the value of x AND what is the value of x?

• X=12

• 8X - 17 + 5X +19 = 180

• 8X - 17 = 5X +19

• X= -12

What is the value of x?

• 27

• 72

• 108

• 153

What is the measure of x?

What is the correct EQUATION to find the value of x?

• 8x - 4 = 180

• 8x - 4 = 60 + 180

• 60 = 8x - 4

• 8x - 4 + 60 = 180

Which equation is parallel to: y = 5/7x +2

• y = -7/5x +1

• y = 7/5x +4

• y = -5/7x -3

• y = 5/7x +5
