A rectangle, possibly a square. Can you see why a parallelogram must be a rectangle if any one of its angles is right?

Except for rectangles, no parallelogram has right angles.

No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).

No, not necessarily. A parallelogram can have all sides equal, but still not be a square.

a square or a rectangle
