a parallelogram with four right angles with sides different in length and width is That would be a rectangle. - HistoryDork
Rhombus
A rhombus.
A parallelogram with equal angles and two pairs of sides of different lengths is a Rectangle. The rectangle is a special case of the parallelogram where the angles are all equal at 90°.

A SQUARE A rectangle satisfies the angles but not the lengths. A rhombus satisfies the length, but not the angles. A parallelogram neither satisfies length nor angles.
It could be either of the following: * Rhombus - A parallelogram with four sides of equal length. * Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).
A Rhombus is a parallelogram with all sides equal in length.
Two examples of parallelograms with no right angles are a rhombus and a generic oblong parallelogram. A rhombus has all sides of equal length but can have angles that are not 90 degrees, while an oblong parallelogram has opposite sides that are equal in length and parallel but also lacks right angles. Both shapes maintain the properties of a parallelogram, including opposite sides being equal and parallel.
The area of a parallelogram (even with unequal adjacent sides) is still the base times the height. But the height is not the length of a side but the distance (at right angles to the base) between the base and the side parallel to it.
A parallelogram in which angles are oblique and adjacent sides are of unequal length.
