Question

if angle l= 60 degree and line m/n, find the measure of all angles​

Answer 1

Answer:

1 = 5 (corresponding angels)

5 = 7 ( Vertically opposite angle)

1 = 3 ( Vertically opposite angle)

=> 1 = 5 = 7 = 3 = 60°

1 + 2 = 180° 【linear pair】

60° + 2 = 180°

2 = 120°

2 = 4 ( Vertically opposite angle )

2= 6 (corresponding angles)

6 = 8 ( Vertically opposite angle )

=> 2 = 4 = 6 = 8 = 120°
