* The length of one [[Median (geometry)|median]] is equal to the [[Circumscribed circle|circumradius]].
* The shortest [[Altitude (triangle)|altitude]] (the one from the vertex with the biggest angle) is the [[geometric mean]] of the [[line segment]]s it divides the opposite (longest) side into. This is the [[right triangle altitude theorem]].
