No, only the square fits both descriptions. A parallelogram has four sides, but no right angles.

Are all paralleograms rectangles?

Some paralleograms are rectangles. A right paralleogram is a rectangle. In the case of a rectangle, all angles formed by the sides are right angles and opposite sides are parallel. The sum of adjacent angles in a parallelogram is 180 degrees.


How do I know my parallelogram is not a rectangle?

A rectangle - has four right-angles at the corners. A Parallelogram - has no right-angles, but has opposite angles equal. Technically - a rectangle is a parallelogram, but a parallelogram can never be a rectangle. Clarification - Actually, all rectangles are parallelograms, but not all parallelograms are rectangles. The definition of a parallelogram is that of a four-sided shape where the opposite sides are parallel. There is no angle-size limitation in the definition. Squares, rectangles and rhombuses are all parallelograms.


Does a parallelogram have four right angles?

Not necessarily. A parallelogram is a quadrilateral with 2 sets of 2 parallel sides. Only rectangles and squares have right angles as all four angles - a rectangle is a "special" parallelogram that has all four angles equal; a square is a "special" rectangle that has all four sides of equal length.


Are rectangles a parallelogram?

Yes - since the definition of a parallelogram is "...a quadrangle with opposite sides and angles equal..."


Why are all rectangles examples of parallelograms but all parallelograms are not rectangles?

To be a parallelogram, the figure needs both sets of opposite sides to be parallel. A rectangle needs to have four right angles. This means the rectangle has to be a parallelogram. However, you can have opposite sides parallel without having right angles, as long as opposite angles are equal to each other,


Can a parallelogram be a rectangle rhombus and square?

No, because a rectangle has four sides, and four right angles. So does a square. But, a rhombus has four sides, two obtuse angles, and two acute angles. Even though a rhombus does qualify as a parallelogram, (four sides, four angles) is does not qualify as a rectangle or square because is doesn't have four right angles. All squares are rectangles, but not all rectangles are squares because a rectangle has four sides, and four right angles, but with a square, all the sides have to be the same length.


Why are squares and rectangles called parellelograms?

A parallelogram is a quadrilateral (four sided shape) which has two pairs of opposite sides that are parallel. In a square, the opposite sides are parallel, thus a square is also a parallelogram In a rectangle, the opposite sides are parallel, thus a rectangle is also a parallelogram. A rectangle is a parallelogram in which [all] the angles are right angles. A square is a rectangle (and thus a parallelogram) in which all the sides are the same length as well as all the angles being right angles.


How are parallelograms different from rectangles?

All parallelograms do not have 90 degree angles. Those that do are called rectangles, a special subgroup within the term.All that is required of a parallelogram is that opposite sides are parallel. Another special case of parallograms is the rhombus, a parallelogram with 4 equal sides but no right angles.A parallelogram is a 4-sided polygon where the opposite sides are parallel. A rectangle is a type of parallelogram, but it has the added requirement that all angles are right angles (90°).Sometimes the term parallelogram is used to indicate that a regular quadrilateral is not a rectangle, but has two pairs of identical angles.Rectangle is "a parallelogram with one right angle", (which means all angles are right)


A parallelogram with no right angles an four congruent sides?

A parallelogram with no right angles and four congruent sides is a Rhombus.


All rectangles have four right what?

Rectangles have four sides and four angles.


A rectangle is a parallelogram with how many sides?

All rectangles have 4 sides. All parallelograms have 4 sides. A rectangle is a parallelogram with all 4 angles of 90°


A parallelogram with 4 equal sides but no right angles?

A parallelogram with four equal sides and no right angles is a rhombus.
