A parallelogram has ___ sides 13. Yes. A square however is a rhombus since all four of its sides are of the same length. If the quadrilateral is convex or concave (that is, not self-intersecting), then the area of the Varignon parallelogram is half the area of the quadrilateral. Finally, a polygon is a closed, two-dimensional shape with many sides. Thus all parallelograms have all the properties listed above, and conversely, if just one of these statements is true in a simple quadrilateral, then it is a parallelogram.
