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.

The quadrilateral would have to be a parallelogram which is not also a rectangle or a rhombus.
No, a parallelogram does not have perpendicular sides by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Perpendicular sides would form a right angle, which is a characteristic of rectangles, squares, and other types of quadrilaterals, but not parallelograms.
Two, a square and a trapezoid. A square is a rectangle and a parallelogram.
A parallelogram is a quadrilateral in which each of two sets of opposite sides consists of two parallel lines (or for math purists I should say, parallel line segments).
It is not possible to have a quadrilateral with four parallel sides - this would bea series of four parallel lines that do not intersect.A quadrilateral with four sides of equal length is a rhombus, however.And a quadrilateral with 2 pairs of parallel sides is a parallelogram.
