A parallelogram is a quadrilateral with two sets of opposite sides.
Other than a rectangle (or a square), this would be a rhombus or diamond shape.
A quadrilateral with only one set of parallel sides is a trapezoid (trapezium in the UK).

Rectangle
Yes, every rectangle is a parallelogram. Parallelograms are defined as a shape with opposite, but parallel sides. A rectangle is defined as a shape with 90 degree angles, 2 sets of parallel sides, and the opposite sides must be equal in length. Because the sides of any rectangle are parallel, any qualified rectangle is a parallelogram.
