Question

In a Parallelogram, one of the angles is 60°. Find the measure of

each angle.​

Answer 1

Answer:

Let ABCD is a parallelogram in which

∠A=60∘

We know, In parallelogram Opposite angles are equal .

So ∠C=60∘

Also, In parallelogram adjacent sides sum up to give 180∘

So ∠A+∠D = 180∘

∠D = 180−60=120∘

So ∠A+∠B=180∘

∠B=180−60=120∘

Therefore, < A = 60∘

< B = 120∘

< C = 60∘

< D = 120∘
