====Medians====

Each of the three [[Median (geometry)|medians]] of a triangle is a line segment going through one [[Vertex (geometry)#Of a polytope|vertex]] and the midpoint of the opposite side, so it bisects that side (though not in general perpendicularly). The three medians intersect each other at a point which is called the [[Centroid#Of triangle and tetrahedron|centroid]] of the triangle, which is its [[center of mass]] if it has uniform density; thus any line through a triangle's centroid and one of its vertices bisects the opposite side. The centroid is twice as close to the midpoint of any one side as it is to the opposite vertex.
