median


The median of a triangle is a line segmentMathworldPlanetmath joining a vertex with the midpointMathworldPlanetmathPlanetmathPlanetmath of the opposite side.

In the next figure, AA is a median. That is, BA=AC, or equivalently, A is the midpoint of BC.

If the length of the three sides of the triangle are known, the length of the medians can be found by means of Apollonius theoremMathworldPlanetmath.
