Question

If the ratio of measure of two adjacent angles of a parallelogram is 1:2 find the measure of all angles of the parallelogram

Answer 1

Answer:

60,120,60,120

Step-by-step explanation:

let 1:2 be 1x:2x

sum of all angles in parallelogram = 360° ( property )

as opposite angles are equal in parallelogram

1x+2x+1x+2x = 360°

6x = 360°

x = 360°/6

x = 60°

so,

1st angle = 60°

2nd angle = 120°

3rd angle = 60°

4th angle = 120°
