Yes a rectangle is a special case of the parallelogram (one where any and all angles are 90°). Parallelograms are sometimes rectangles, but not always.
The parallelogram is itself a special case of the trapezoid where at least one pair of opposite sides is parallel.
the trapezoid is a special case of the quadrilateral, a planar convex figure with four sides.
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.
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Some parallelograms are rectangles; all rectangles are parallelograms.
All rectangles are parallelograms, so yes there are some.
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
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. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
Yes: PARALLELOGRAMS can be rectangles. The difference is that rectangles must have one right angle, so not all parallelograms are rectangles, but all rectangles are parallelograms, by defiinition. Parallegram doesn't define anything in the English vocabulary.
