Such a quadrangle cannot exist. The right angle must be formed by one of the parallel sides and one of the non-parallel sides. Then the angle formed at the other end of that non-parallel side would also be a right angle (the non-parallel side would be a transversal intercepting the two parallels). But then the quadrangle has two right angles, and not just one. No its Trapezoid
A rhombus for example
Three sets of two
A square is an example of four sided figures with the opposite sides parallel. While all sides have one side that is parallel to the opposing side, the sides are all other parallel to each other. Mathmaticaly speaking each side of the square has one parallel side opposing it and an orthogonal side at each of its ends. The square shares this property with other rectangles
One side cannot be parallel because parallel is a relationship between two lines (or sides). A square has two pairs of parallel lines.

A quadrilateral with two sets of parallel side and right angles is called a rectangle. If all the sides are the same size it is also called a square.
Any parallelogram, including rhombus, but not including rectangle or square.

A square is a parallelogram because it has two sets of parallel sides. It's a rhombus because every side is the same length.
A square has four parallel sides (two pairs of parallel sides).
parallelagram http://en.wikipedia.org/wiki/Parallelagram well specifically you would be a rectangle which has parallel sides like a square. a parallelogram can be a square or a rectangle because they all have parallel sides but only squares and rectangles have right angles on all sides. parallelograms have congruent sides which require acute and obtuse angles.
a trapezoid would work as long as there is still one set of parallel lines and one set of non-parallel lines.
You are a square?
Three sets of two
Just draw one! It can help if all the sides are different lengths. Draw three of the sides, making sure that the first and third sides are not parallel, then draw the fourth side, making sure it is not parallel with its opposite side.
