A Tour of Triangle Geometry
by Paul Yiu
Publisher: Florida Atlantic University 2005
Number of pages: 52
In this paper we outline some interesting results with illustrations made by dynamic software. We shall center around the notions of reflection and isogonal conjugation, and introduce a number of interesting triangle centers, lines, conics, and a few cubic curves.

Axioms were uncovered in Euclid's geometry. These discoveries were organized into a more rigorous axiomatic system by David Hilbert in his Grundlagen der Geometrie (1899) which contained his definitive set of axioms for Euclidean geometry.
