Question

Use the figure to find the measures of the numbered angles.

Answer 1

1 = 61° because it is a corresponding angle to angle 6

2 = 119° because it is an alternate exterior angle to angle 7

3 = 61° because it is an alternate angle to angle 1

4 = 119° because it is an alternate angle to angle 2

5 = 119° because it is an alternate angle to angle 7

6 = 61° because is is an alternate angle to 61°

7 = 119° because it and 61° are supplementary angles (total 180° together)

Explanation:

Answer 2

1 = 61° because it is a corresponding angle to angle 6

2 = 119° because it is an alternate exterior angle to angle 7

3 = 61° because it is an alternate angle to angle 1

4 = 119° because it is an alternate angle to angle 2

5 = 119° because it is an alternate angle to angle 7

6 = 61° because is is an alternate angle to 61°

7 = 119° because it and 61° are supplementary angles (total 180° together)
