8
Alternate Exterior Angles Name the angle relationship Are they congruent or supplementary? Find the value of x 125 t 5x 5x = 125 5 x = 25

9
Corresponding Angles Name the angle relationship Are they congruent or supplementary? Find the value of x 2x + 1 t 151 2x = 150 2 x = 75 2x + 1 = 151 - 1

10
Consecutive Interior Angles Name the angle relationship Are they congruent or supplementary? Find the value of x 81 t 7x + 15 supp 7x = 84 7 x = 12 7x + 96 = 180 - 96 - 96 7x + 15 + 81 = 180
