A square is a rectangle and a rectangle is a parallelogram and a parrallelogram.
parrallelogram
A parallelogram with a right angle is a rectangle.
parrallelogram and quadrilateral
Such a parallelogram is a rectangle.
A rectangle has four 90-degree angles.
A parallelogram is a quadrilateral with two pairs of parallel sides. A rectangle meets those requirements.
There is no reason because the premise is false: a parallelogram is not a rectangle.
A parallelogram with 4 right angles is a rectangle.
Yes, a rectangle is a special case of a parallelogram, where each of the 4 angles = 90°

Except for the special case of a rectangle, a parallelogram must have two acute angles.
