Presentation transcript:

Geometry 3-2 Angles and Algebra Label the type of angle pair, then find the value of x. Alternate Interior 110° (2x-10)° 2x – 10 = 110

Example Alternate Exterior 7x – 20 = 50 Label the type of angle pair, then find the value of x. Alternate Exterior 50° (7x-20)° 7x – 20 = 50

Example Corresponding 2x – 10 = 4x – 30 Label the type of angle pair, then find the value of x. (4x-30)° (2x-10)° Corresponding 2x – 10 = 4x – 30

Example Same-Side Interior 3x + 16 + 14x – 6 = 180 Label the type of angle pair, then find the value of x. (14x-6)° (3x+16)° Same-Side Interior 3x + 16 + 14x – 6 = 180

Example Same-Side Exterior 2x + 5 + 55 = 180 Label the type of angle pair, then find the value of x. 55° (2x+5)° Same-Side Exterior 2x + 5 + 55 = 180

Example Corresponding 30x = 90 x = 30 Alternate Exterior x + y = 90 Label the type of angle pair, then find the values of x and y. (x + y)° (30x)° Corresponding 30x = 90 x = 30 Alternate Exterior x + y = 90 (30) + y = 90 y = 60
