Take your pick: square, rectangle, rhombus or parallelogram which all have opposite parallel sides
Only if it is a trapezoid (US usage) with one set of parallel sides, or a parallelogram with both sets of opposite sides parallel. The term quadrilateral only means that the shape has 4 sides.
a square
A quadrilateral that has two sets of equal sides but is not a parallelogram is a kite. In a kite, two pairs of adjacent sides are equal in length, but the opposite sides are not parallel. This distinct property differentiates it from parallelograms, where opposite sides are both equal and parallel. Kites also have unique angle properties, such as one pair of opposite angles being equal.
Trapezoid

Trapezoid is the quadrilateral which have no parallel sides.
A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel
a square
The practical answer is a parallelogram, which has two sets of parallel opposite sides and two sets of equal opposite angles. This includes rhombi, rectangles, and squares.A trapezoid (trapezium) has one set of parallel opposite sides that are not equal, but may have non-parallel opposite sides equal in length (isosceles trapezoid).
A parallelogram is a quadrilateral with two sets of opposite sides.Other than a rectangle (or a square), this would be a rhombus or diamond shape.A quadrilateral with only one set of parallel sides is a trapezoid (trapezium in the UK).

Any quadrilateral with two sets of parallel sides is called a parallelogram.
A quadrilateral is a polygon with four 'sides' . A parallelogram is a quadrilateral with two sets of parallel sides.
