Note: Centroid is the point of intersection of the medians of the triangle and it is denoted by G. Centroid divides the median in the ratio 2:1.
Let A = (x1, y1, z1) , B = (x2, y2, z2) and C = (x3, y3, z3) be the vertices of the triangle ABC. Let AD be the median drawn from A. Then D is the mid-point of BC.
Let G be the centroid of the ΔABC. median AD in the ratio 2 : 1.
∴ The coordinates of G are,
