Parallel Lines Cut by a Transversal and Triangle Properties

What are angles 1 and 7?

• Alternate Interior Angles

• Same Side Interior Angles

• Alternate Exterior Angles

• Corresponding Angles

Answer explanation

Alternate Interior Angles are angles inside the parallel lines and on opposite sides of the transversal. They are congruent (equal in measure).

Given m∠8=48^o, what is m∠2.

Answer explanation

Alternate Exterior Angles are congruent (equal in measure).

Answer explanation

Vertical Angles are non-adjacent angles that are across from each other in intersecting lines. They are congruent (equal in measure).

Answer explanation

Corresponding Angles are in the same relative position (matching corners) and congruent (equal in measure).

A line that passes through parallel lines is called a ______________.

• vertical lines

• a passer through line

• transversal

• perpendicular line

WHAT IS THE CORRECT EQUATION TO FIND THE VALUE OF X?

• X=12

• 8X - 17 + 5X +19 = 180

• 8X - 17 = 5X +19

• X= -12

WHICH IS THE CORRECT EQUATION TO SOLVE FOR X?

• 16X+180 = 90

• 12X - 29 = 4X +1

• 12X - 29 + 4X +1=90

• 12X - 29 + 4X +1=180

WHAT IS THE CORRECT EQUATION TO USE TO SOLVE FOR X?

• 33 = 7X +5

• -7X=33

• 33+7X+5=180

• 33+7X+5=90

Which of these angles is NOT congruent to angle 5?

• Angle 6

• Angle 8

• Angle 1

• Angle 4

Find the measure of angle 4

• 27^o

• 153^o

• 63^o

• 90^o
