Some parallelograms are rectangles; all rectangles are parallelograms.
parallelograms.
squares, rectangles, rhombuses
rectangles,rhombus,and a square
no because it is a Parallelogram^That is quite an incorrect answer. Rectangles are parallelograms, but a parallelogram may not be a rectangle.All rectangles have 4 corners.Besides the point, to the original answerer, all parallelograms also have 4 corners...
No. Most parallelograms are not rectangles. But every rectangle is a parallelogram.
Some parallelograms are rectangles; all rectangles are parallelograms.
parallelograms.
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Yes.

No because rectangles have to have right (90 degree) angles.
Every rectangle has four (straight) sides, and four (right) angles. All rectangles are also polygons, quadrilaterals, and parallelograms.
All rectangles are also categorized as parallelograms. If a parallelogram has one of its angles equal 90°, then all four angles are 90° and it is a rectangle.
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.
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
