Does the Klehr-Bliss Point [http://math.missouristate.edu/44605.htm](http://math.missouristate.edu/44605.htm) lie on the Euler Line? > **[Euler line](https://en.wikipedia.org/wiki/Euler_line)** > > In geometry, the Euler line, named after Leonhard Euler (/ˈɔɪlər/), is a line determined from any triangle that is not equilateral. It is a central line of the triangle, and it passes through several important points determined from the triangle, including the orthocenter, the circumcenter, the centroid, the Exeter point and the center of the nine-point circle of the triangle. > The concept of a triangle's Euler line extends to the Euler line of other shapes, such as the quadrilateral and the tetr... ---

In general, no. As the first article points out, the Klehr-Bliss point depends on the coordinate system and as the coordinate system changes, the Klehr-Bliss point sweeps out the [nine-point circle](http://en.wikipedia.org/wiki/Nine-point_circle); therefore, it can’t possibly lie on the Euler line except in at most two coordinate systems.
