Explain why it is not possible to draw a square that is not a parallelogram.

Because all the sides have to be even to make a square if it wasn't then it wouldn't be a square

Because in a parallelogram, the opposite sides are parallel and congruent, opposite angles are congruent, diagonals bisect each other, basically all the things that squares also have. That is why it is impossible to draw a square that is not a parallelogram.
