The main difference between a rectangle and a parallelogram that makes rectangle a special case of the parallelogram is the fact that all the angles of a rectangle are equal to 90 degrees. This is not the case in a parallelogram because the adjacent angles are only supplementary to each other.

They are not all rectangles because a rectangle is a special case of a parallelogram where all angles = 90 degrees.
In fact, some are rectangles, but not all are.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
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.
Are all rectangles parallelograms
