No. Only some parallelograms are rectangles. But all rectangles are parallelograms.

All normal rectangles, are parallelograms.

All rectangles are parallelograms, so yes there are some.

Yes, thet's true. Rectangles are special kinds of parallelograms. So all rectangles are parallelograms, but there are other parallelograms that are not rectangles.

Some parallelograms are rectangles; all rectangles are parallelograms.

In fact, some are rectangles, but not all are.

Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.

Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.

By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.

No. All rectangles are parallelograms. However, not all parallelograms are rectangles.

yes. rectangles are just the special cases of parallelograms where the angles are all 900

No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.

Some are, most are not. On the other hand, all rectangles are parallelograms.

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.

All rectangles are indeed parallelograms.

the three special quadrilaterals that can be a parallelogram are a rectangle, a square, and a rhombus Actually, this is incorrect. All squares are rectangles. All rectangles are parallelograms. Therefore all squares are parallelograms. But not all parallelograms are rectangles. And not all rectangles are squares.

Yes. All rectangles are parallelograms.A parellelogram is defined as a figure in which both pairs of opposite sides are parallel.A rectangle can also be described as a quadrilateral parallelogram, or an equiangular parallelogram because all of its angles are 90 degrees.However, although all rectangles are parallelograms, it is important to remember that not all parallelograms are rectangles.All rectangles and parallelograms are 4 sided quadrilaterals

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.

Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.

Not necessarily. All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms. Parallelograms are more specific instances of quadrilaterals. Its like saying all squares are rectangles but not all rectangles are squares.

In all parallelograms, opposite angles are equal and the 4 interior angles add up to 360 degrees. In someparallelograms, all of the angles are 90 degrees. These parallelograms are rectangles.

A trapezoid is any quadrilateral (four sided figure) with two parallel sides. All rectangles are parallelograms, and all parallelograms are trapezoids. However, only some trapezoids are rectangles.
