The Apollonius circle and related triangle centers - Milorad Stevanovic We give a simple construction of the Apollonius circle without directly invoking the excircles. This follows from a computation of the coordinates of the centers of similitude of the Apollonius circle with some basic circles associated with a triangle. We also find a circle orthogonal to the five circles, circumcircle, nine-point circle, excentral circle, radical circle of the excircles, and the Apollonius circle. ✪ ✪ ✪ ✪ ✪ Hidden Content: **Hidden Content: Content of this hidden block can only be seen by members of (usergroups: V.I.P Downloader).** Theo LTTK Education
