In parallelogram abcd, d is a right angle. is abcd a rectangle?

a. no

b. yes

c. cannot be determined

B. Yes

Step-by-step explanation:

We have been given that in parallelogram ABCD, D is a right angle. We are asked to determine whether the given parallelogram is rectangle or not.

Let us recall parallelogram properties.

Opposite angles of parallelogram are equal.

Consecutive angles of parallelogram are supplementary.

Since D is a right angle, so its opposite angle will be right angle as well and consecutive angles of angle D will be right angles as well.

Therefore, the parallelogram ABCD is a rectangle and option B is the correct choice.
