【Abstract】 Doliwaka and Lassak proposed the problem of convex n-gon′s relatively sides.Convex hexagon is discussed.Convex hexagon H in a parallelogram P.Based on the ratio of the corresponding sides of P and H,show that every convex hexagon has a relatively long side and every convex hexagon with pair of parallel sides has a relatively short side.更多还原
