A rectangle - has four right-angles at the corners. A Parallelogram - has no right-angles, but has opposite angles equal. Technically - a rectangle is a parallelogram, but a parallelogram can never be a rectangle.

Clarification - Actually, all rectangles are parallelograms, but not all parallelograms are rectangles. The definition of a parallelogram is that of a four-sided shape where the opposite sides are parallel. There is no angle-size limitation in the definition. Squares, rectangles and rhombuses are all parallelograms.
