Webthe Feuerbach point Z, the point where the incircle touches the nine-point circle. Once we have proven parts 1)-3) of this theorem, the proof of 4) is easy. This is because an a ne map takes tangent lines to a conic to tangent lines of the image conic. Since is a homothety, and Zis xed, will x the tangent line tto N at Z.
In the geometry of triangles, the incircle and nine-point circle of a triangle are internally tangent to each other at the Feuerbach point of the triangle. The Feuerbach point is a triangle center, meaning that its definition does not depend on the placement and scale of the triangle. It is listed as X(11) in Clark Kimberling's Encyclopedia of Triangle Centers, and is named after Karl Wilhelm Feuerbach.
