From wiki.gis.com. Centroid of a triangle. In geometry, the centroid, geometric center, or barycenter of a plane figure X is the intersection of all straight lines that divide X into two parts of equal moment about the line. Informally, it is the “average” of all points of X.

The centroid (a.k.a. the center of mass, or center of gravity) of a polygon can be computed as the weighted sum of the centroids of a partition of the polygon into triangles. The centroid of a triangle is simply the average of its three vertices, i.e., it has coordinates (x1 + x2 + x3)/3 and (y1 + y2 + y3)/3.
