No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
All rectangles are parallelograms, so yes there are some.
Some parallelograms are rectangles; all rectangles are parallelograms.
yes
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
In fact, some are rectangles, but not all are.
All of them are.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
Some are, most are not. On the other hand, all rectangles are parallelograms.
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.
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also 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.
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.
