Answer 1

QUESTION:

• Find the angles of a parallelogram ABCD in which angle A =2 angle B

SOLUTION:

Given : angle A = 2 angle B

We know in parallelogram,

the adjacent angles have sum 180°

A and B are adjacent angles

So,angle A + angle B = 180°

2B + B = 180°

3B = 180B

= 60°

A= 2 × 60°

= 120°

A = C = 120° ( opposite angle of parallelogram)

B = D = 60° ( opposite angle of parallelogram)
