摘要：

Let K be a convex body in the plane. Cut K by a line passing through its centroid. It is a well-known result, due to Winternitz, that the areas of the resulting two pieces are at least 4/9 times the area of K and at most 5/9 times the area of K. We generalize this inequality to the case when the body is cut by a line not passing through the centroid. As an application we obtain a discrete version of Winternitz's theorem.
