Yes.
A parallelogram is any 4-sided figure where the opposite sides are parallel. Only the special case where all four angles are 90° do you have a rectangle.
To visualize, picture a cardboard box, closed on top, and open on two sides. Move the top so that it is leaning a little, and both open sides are parallelograms.

What else can I help you with?
Are some parallelograms rectangles?
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
There are some parallelograms that are rectangles?
True
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
