Extract
If A, B, C, G are four given points in a plane, it is possible to place masses x, y, z at A, B, C respectively, so that the centroid of the system is at G. This, it is to be observed, can only be done in one way as x, y, z must be proportional to the areal (or “barycentric”) co-ordinates of G with respect to the triangle ABC.
