Rhombus
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.
a parallelogram with four right angles with sides different in length and width is That would be a rectangle. - HistoryDork
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 parallelogram is always a "pushed over square". However a square implies 4 angles of 90 degrees (and 4 sides of equal length); a parallelogram has no angles that are 90 degrees, so really a parallelogram is never a square (even if the sides are all equal length).* * * * *Yet another horrendously incorrect answer by "The Community"!A parallelogram is NOT a "pushed over square". All four sides of a square are the same length. This is NOT necessarily true of a parallelogram.A parallelogram CAN have angles of 90 degrees and so a parallelogram CAN be a square.A parallelogram is a square in the sense that they are both 4 sided quadrilaterals but they both have different geometrical properties
A Rhombus is a parallelogram with all sides equal in length.
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
A parallelogram in which angles are oblique and adjacent sides are of unequal length.
A parallelogram has two sets of parallel sides. It can have four sides that are equal in length. That is why a square is also a parallelogram. You can have a parallelogram with two sets of parallel sides, all of which are equal in length, but they do not meet in right angles. It looks kind of like a lopsided or squished square, and it is called a rhombus.
