Step-by-step explanation:
 We know that a square is quadriteral whose sides are equal.
 By definition, a square has the following properties:
 1) Its four sides are congruent.
 2) The diagonals are congruent.
 3) The angles formed by the intersection of the diagonals measure 90 degrees.
 4) The opposite sides are parallel.
 5) Each internal angle measures 90 degrees.
