Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
All parallelograms are rectangles Always, Sometimes, or Never?
Never, honey. Just because a parallelogram has those fancy opposite sides that are parallel, doesn't mean it automatically becomes a rectangle. Rectangles have those nice right angles, while parallelograms can be all slanted and sassy. So, keep those shapes in check, darling.
Can a parallelogram also be a rectangle?
Some parallelograms are rectangles; all rectangles are parallelograms.
Are there some parallelograms that are rectangles?
All rectangles are parallelograms, so yes there are some.
Is every property of parallelograms also a property of all rectangles?
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
