Explain how a square is

**(i)** a quadrilateral

**(ii)** a parallelogram

**(iii)** a rhombus

**(iv)** a rectangle.

**(i)** A square is 4 sided, so it is a quadrilateral.

**(ii)** A square has its opposite sides parallel, so it is a parallelogram.

**(iii)** A square is a parallelogram with all the four sides equal, so it is a rhombus.

**(iv)** A square is a parallelogram with each angle a right angle, so it is a rectangle.
