A rectangle has 4 equal, 90 degree angles (one at each corner). A parallelogram may not have all equal angles. Imagine a rectangle that whose opposite corners were pulled so that it had two slanted, but parallel sides, and two straight and parallel sides. That is what some parallelograms look like. A rectangle, however, is a type of parallelogram. You can see a picture of a non-rectangular parallelogram, by clicking on the related link.
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.
No. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
In fact, some are rectangles, but not all are.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.

No. 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.
