Question

In the quadrilateral ABCD,the angles A,B,C,D are in the ratio 1:2:1:2, then what are the measures of all angles of quadrilateral ?​

Answer 1

Step-by-step explanation:

Sum of all angles of a quadrilateral = 360°

1x + 2x + 1x +2x = 360

6x = 360

X=60

so the angles are = 1x60 = 60°

2x = 2×60=120

1x 60 =60

2x= 2×60 = 120

60°, 120°, 60°,126 Ans
