Properties: HG=2GO, ON=NH, OG=2GN, NH=3GN. ​ Relative distances of triangle centers. The red line is twice as long as the green line, and the blue line is three times as long as the green line. Applications: One important consequence of the Euler line is that information about any one of the centroid, orthocenter, and circumcenter can be derived from information about the other two.
