Q16 of 50 Page 220

If the origin is the centroid of a triangle ABC having vertices A (a, 1, 3), B (– 2, b, – 5) and C (4, 7, c), find the values of a, b, c.

Given; Triangle ABC having vertices A (a, 1, 3), B (– 2, b, – 5) and C (4, 7, c) and origin is the centriod.

For a triangle the coordinates of the centroid is given by the average of the coordinates of its vertices.
