Is it true that all the faces of a quadrangular prism are parallelograms?

This is true only in a few cases. The side faces of the prism are always parallelograms. But any quadrangular figure can lie at the base. If it is parallelogram (in particular a rectangle, square or rhombus), then the answer is yes, right. But if the bases of the prism are two trapezoids, then this judgment is erroneous. After all, a trapezoid is not a parallelogram.
