Angle Pairs Parallel Lines and Transversals

Which angle pairs are always congruent?

• Linear Pair, Same Side Interior, Same Side Exterior

• Vertical, Alternate Interior, Alternate Exterior, Corresponding

• 140^o

• 180^o

• 40^o

• 160^o

How would you set up to solve for x?

• 6x = 60

• 6x + 60 = 180

How would you set up to solve for y?

• 120 = 6y

• 120 + 6y = 180

How would you set up to solve for x?

• 10x - 23 = 137

• 10x - 23 + 137 = 180

How would you set up to solve for x?

• 38x - 1 = 75

• 38x - 1 + 75 = 180

Solve for x:

38x - 1 = 75

• 4

• 2

• 6

• 7

Solve for x:

6x = 60

• -11 ; alternate interior angles

• 10 ; corresponding angles

• 9 ; same side interior angles
