Notes
Properties of Square:

The sides of a square are congruent.

A square is a rectangle with equal sides. This means a square has all the properties of a rectangle with an additional requirement that all the sides have equal length.

The opposite sides of a square are parallel.

The adjacent sides are perpendicular to each other.

The angles of a square are all congruent and equal to 90°.
 The Sum of all angles of the square is 360°.
 In a square the diagonals.
(i) bisect one another .......(square being a parallelogram)
(ii) are of equal length .......(square being a rectangle) and
(iii) are perpendicular to one another.
