    A square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. But not every rectangle is a square, to be a square its sides must have the same length.

    For the same reason that a man is always a person but a person

    is not always a man.

    And the same reason that a 5th grader is always a student but a student

    is not always a 5th grader.

    A square is a special kind of rectangle ... one with all equal sides. If all the

    sides are not equal, then it's still a rectangle, but it's no longer the 'special'

    kind of rectangle.
