Triangle Centroid

The geometric centroid (center of mass) of the polygon vertices of a triangle is the point (sometimes also denoted ) that is also the intersection of the triangle's three triangle medians. The point is therefore sometimes called the median point. The centroid is always in the interior of the triangle (from Wolfram MathWorld).
