an perticulogram
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
a rhombusNotice that if all 4 sides are equal, then they must be parallel.
Square. Square is a quadrilateral and all sides are equal and opposite sides are parallel, the sum of the interior angle measure 3600.
If both sets of opposite sides are parallel and not equal, the shape cannot be a plane figure. It must be a projection of a parallelogram onto a spherical surface (or similar).

A parallelogram.
A rhombus has all sides equal and opposite sides parallel. This includes a square which is a special case of a rhombus with all angles equal (90 degrees) as well. If opposirte sides are equal but not all sides are equal, it is a parallelogram
