No. A square fits the classification of a quadrilateral and a parallelogram, but that isn't necessarily the definition. A rhombus is a quadrilateral and a parallelogram, and so are other irregular quadrilaterals. The correct definition would be a parallelogram and a quadrilateral with four right angles and all equal sides.
