    Well, no sketches here.

    1) A parallelogram has two sets of parallel sides. A trapezium does not.

    2) A rhombus is a quadrilateral with 4 congruent sides (i.e., they all have the same length). A square is a special rhombus (so it has 4 congruent sides) in which every angle is a right angle (i.e., measures 90 degrees).

    That's as succinct as it gets, I suppose.

    Mathnasium has given a set of valid definitions. Here are equivalent definitions:

    1. In a parallelogram opposite angles are equal - in a trapeziums not.

    2. A square is a rhombus whose diagonals have equal length.
