TRAPEZOID
There is nothing because if the shape has only four sides and that means two sets that are parallel, the angles will have to be right ones. Unless it's not a polygon that is. I take it back maybe a parallelogram.
A rectangle is a four sided polygon with four right angles and two pairs of parallel side. [Equal sides is not required since it is implied by parallel and right angles].
