In triangle geometry, a median of a triangle is a line joining one vertex to the midpoint of the opposite side.
Properties
- The medians of a triangle are concurrent, and their common point is the centroid or barycentre of the triangle: this common point divides each median in the ratio 2:1.
- The three medians divide the triangle into six regions of equal area.
