## Dr. Branislav Kisačanin – Geometry of Triangles

April 16, 2013 by Metroplex Math Circle

This Saturday, April 20th Dr. Kisačanin will return for another of his fantastic lectures. Triangles factor into almost every math contest in addition to being endlessly fascinating objects in themselves. Here is Dr. Kisačanin’s description of the session with links to resources:

In this talk about geometry of triangles we will see two different proofs of Stewart’s theorem, derive formulas for important cevians, and solve several interesting geometric problems.

We will also look at other important points in triangles (Fermat point, centers of excircles, …) and look at the Euler line, the nine-point circle, and related problems.
