The nine-point center N lies on the Euler line of its triangle, at the midpoint between that triangle's orthocenter H and circumcenter O. The centroid G also lies on the same line, 2/3 of the way from the orthocenter to the circumcenter, so Thus, if any two of these four triangle centers are known, the positions of the other two may be determined from them.
