  About ikleyn: Sum of vectors connecting the center of mass of a quadrilateral with its verticesProve yourself that for any quadrilateral in a plane the sum of the vectors connecting the center of mass of the quadrilateral with its vertices is equal to zero. In a coordinate plane, the center of mass of a quadrilateral with vertices P=P(x1,y1), Q=Q(x2,y2), R=R(x2,y2) and S=S(x4,y4) is the point with the coordinates The center of mass of a quadrilateral is called sometimes a centroid or a barycenter of the quadrilateral. Tip: Use the component form of vectors in a coordinate plane (see the lessons Vectors in a coordinate plane and Addition, Subtraction and Multiplication by a number of vectors in a coordinate plane under the topic Introduction to vectors, addition and scaling of the section Algebra-II in this site). If you want to see this Problem solved, find the solution in the lesson Sum of vectors connecting the center of mass of a n-sided polygon qith its vertices under the topic Introduction to vectors, addition and scaling of the section Algebra-II in this site. Note. For any parallelogram, the center of mass coincides with the intersection point of the parallelogram's diagonals. This is proved in the lesson The Centroid of a parallelogram is the Intersection point of its diagonals under the topic Geometry of the section Word problems in this site.
