Question

In a parallelogram ABCD,.<A=60`.what will be the measure of <D​

Answer 1

As AB and CD are parallel to each other and AD and BC arr transversal .

So Angle A + B = 180°

A = 60°

60° + B = 180°

B = 180° - 60°

B = 120°

You know opposite side are equal to each other in ||gm

A = C = 60°

B = D = 120°

Hope its helps you ❤️
