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. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Parallelograms are in the same class as rectangles because they are both 4 sided quadrilaterals.
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.
Yes, all rectangles can be considered parallelograms since they have opposite sides that are parallel to each other.
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.
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.
