Jan Vonk, The Feuerbach point and reflections of the
Forum Geometricorum, 9 (2009) 47--55.
Abstract: We investigate some results related to the Feuerbach
point, and use a theorem of Hatzipolakis to give synthetic proofs of the
facts that the reflections of OI in the sidelines of the intouch and medial
triangle all concur at the Feuerbach point. Finally we give some results
on certain reflections of the Feuerbach point.
