A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.
