Help me with this,.,.please
Given a triangle with vertices at A,B,C, show that the point R = 1/3 (A+B+C) lies on each of the medians. thnx
Refer to the figure that I have attached. Take the median drawn from the point A as AD. Let $\displaystyle (x_a,y_a),(x_b,y_b)\mbox{ and }(x_c,y_c),$ be the coordinates of the vertices A,B and C respectively. Find the coordinates of D and then find the coordinates of E. I am sure you will be able to do this now.
