**Euler Line** lineThe Euler line of a triangle is a line going through several important triangle centers including the orthocenter circumcenter centroid and center of the nine point circle **Euler Line** mathopenref eulerline htmlIn the 18th century the Swiss mathematician Leonhard Euler noticed that three of the many centers of a triangle are always collinear that is they always lie on a straight line This line has come to be named after him the Euler line His name is pronounced the German way oiler

mathworld wolfram Triangles Triangle LinesThe Euler line intersects the Soddy line in the de Longchamps point and the Gergonne line in the Evans point The isogonal conjugate of the Euler line is the Jerabek hyperbola Casey 1893 Vandeghen 1965 **Euler Line** djoyce java Geometry eulerline htmlThe Euler Line of a Triangle It s amazing how much geometry there is in the lowly triangle Consider the triangle ABC below colored magenta Several interesting points and lines can be constructed and they all move as you drag about a vertex A B or C of the triangle mathwords e euler line htmEuler Line The line segment that passes through a triangle s orthocenter centroid and circumcenter These three points are collinear for any triangle In addition the distance from the orthocenter to the centroid is twice the distance from the circumcenter to the centroid
