Location of incenters and Fermat points in variable triangles

Metric Geometry 2007-05-23 v2

Abstract

The orthocentroidal circle of a nonequilateral triangle has diameter GH, joining the centroid to the orthocenter. We show that the incenters of triangles with a given Euler line simply cover the interior of the orthocentroidal circle, and that their Fermat points also lie within this circle.
