    The Feuerbach point and reflections of the Euler line - Jan Vonk

    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.
