Question

Is this correct about a Square?
I used a chess board as a real life example.

1.4 right angles
2.4 sides
3.4 Congruent sides
4.2 sets of opposite, congruent angles
5.Diagonals are perpendicular
6.Diagonals bisect the angles
7.Diagonals bisect each other
8.Both pairs of opposite sides are congruent and parallel

Can you tell me if this is right or if I need to add something else.
