The main difference between a rectangle and a parallelogram that makes rectangle a special case of the parallelogram is the fact that all the angles of a rectangle are equal to 90 degrees. This is not the case in a parallelogram because the adjacent angles are only supplementary to each other.

∙ 12y agoThey are not all rectangles because a rectangle is a special case of a parallelogram where all angles = 90 degrees.

Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
Are all rhombuses also rectangles?
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.
Why are all squares rhombuses?
Are all rectangles parallelograms
Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Is every property of parallelograms also a property of all rectangles?
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
Is there a rectangle that isn't a parallelogram?
No. All rectangles are parallelograms. However, not all parallelograms are rectangles.
All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
Can a parallelogram also be a rectangle?
Some parallelograms are rectangles; all rectangles are parallelograms.
Are there some parallelograms that are rectangles?
All rectangles are parallelograms, so yes there are some.
Are all parallelograms and rectangles the same?
No. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
Are all rectangles parallaelgrams?
All rectangles are parallelograms.
Are all rectangles parallegrams?
All rectangles are indeed parallelograms.
Can a parallelogram be a rectangle and a square?
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.
