MEDIANS & CENTROID

MEDIANS & CENTROID. A median of a triangle is a segment from a vertex to the midpoint of the opposite side. The point of concurrency of the three medians of a triangle is called the centroid . It is always inside the triangle. This point is the center of gravity for the triangle.
