Sarah,

NO. A trapezoid is defined (in North America) to be a quadrilateral that has exactly one pair of parallel sides. (This object is called a trapezium in British English.) A quadrilateral with two pairs of parallel sides is called a parallelogram; a parallelogram with right angles is a rectangle.
