Assuming that no transversal line is present, I can present only the statements base on the figures of a parallelogram. A parallelogram is a <span>quadrilateral. They only differ on the number of
their parallel sides. A square has 2 parallel sides and all of its sides are
equal or the same. A rhombus has 2 parallel sides and all of its sides are
equal or only two of its sides are equal. A rectangle has 2 parallel sides. One
parallel side is the same and can be bigger or smaller than the other parallel
side. Trapezoid has only one pair of parallel sides. The other pair is a mirror
to the other. </span>
