Web1. Perspectivity of Feuerbach and incentral triangles In this note we prove some interesting properties of the Feuerbach points of a triangle. Recall that by the famous Feuerbach theorem, the nine-point circle of a triangle is tangent internally to the incircle and externally to each of the excircles. The points of tangency are the Feuerbach ... 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. Feuerbach's theorem, published by Feuerbach in 1822, states more generally that the nine-poin…
