Question

3. In a a parallelogram ABCD angle A: angle B = 1:2, Then find value of angle A​

Answer 1

Answer:

We know opposite angles of parallelogram are equal so

C is opposite to A and D is opposite to C

So let all the angles be

angle A=1x

angle B=2x

angle C=1x

angle D=2x

we know angle A+B+C+D=360°

6x=360°

So, x=60°

angle A=1x=60°

angle B=2x=2×60°=120°
