Question

What are the coordinates of the centroid of a triangle whose vertices are $(x1, y1, z1)$, $(x2, y2, z2)$, and $(x3, y3, z3)?$

Accepted Answer

The centroid of a triangle with vertices $(x1, y1, z1)$, $(x2, y2, z2)$, and $(x3, y3, z3)$ is given by $\left(\frac{x1+x2+x3}{3}, \frac{y1+y2+y3}{3}, \frac{z1+z2+z3}{3}\right)$.
