Trapezoid
Trapezoid is the quadrilateral which have no parallel sides.
parallelogram
a square
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.

Any quadrilateral with two sets of parallel sides is called a parallelogram.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
a rhombus
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
