Answer 1

Let the adjacent angles be ∠A and ∠B.

We know that Opposite angles of a parallelogram are always add upto 180°.

⇒ ∠A + ∠B = 180°

⇒ ∠A + ∠A = 180°{ Given, ∠A = ∠B}

⇒ 2∠A = 180°

⇒ ∠A = 90.

We know that opposite angles are equal.

Therefore, the measure of each angles are:

⇒ ∠A = 90°.

⇒ ∠B = 90°.

⇒ ∠C = 90°.

⇒ ∠D = 90°.
