If any angle of an equilateral quadrangle is a right angle, then all its angles are right angles and it is also a square. In colloquial usage the shape is often described as a diamond or lozenge. In any rhombus opposite sides will be parallel. Thus, the rhombus is a special case of the parallelogram.
