**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 = (x_{1}, y_{1}, z_{1}) , B = (x_{2}, y_{2}, z_{2}) and C = (x_{3}, y_{3}, z_{3}) 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,
