POLYGONS--------------------------------------------------------

A square is both a rhombus (equal sides) and a rectangle (equal angles) and therefore has all the properties of both these shapes, namely:

The diagonals of a square bisect each other.

• The diagonals of a square bisect its angles.

• The diagonals of a square are perpendicular.

• Opposite sides of a square are both parallel and equal.

• All four angles of a square are equal. (Each is 360/4 = 90 degrees, so every angle of a square is a right angle.)

• The diagonals of a square are equal.

It might be worth clarifying that the diagonals of rhombi or rectangles do not bisect their respective angles. The above section could be mistaken to suggest so since you mention that the list of properties is derived from a combination of rectangle and rhombus properties..
