Abstract

In this paper the existence of three circles, which touch the
circumscribed circle and Euler circle of an allowable triangle in
an isotropic plane, is proved. Some relations between these three
circles and elements of a triangle are investigated. Formulae
for their radii are also given.

Keywords

isotropic plane; Thebault's circles
