Graduate & Undergraduate Student Seminar (GAUSS)
Abstract: It can be rather difficult and time consuming to find elegant solutions to geometry problems, especially if one has trouble drawing or visualizing geometric objects. During math competitions where time is a limiting factor, this makes questions related to geometry some of the most challenging problems to answer. Fortunately, test writers often create questions that utilize only a handful of elementary techniques, such as mass point geometry or barycentric coordinates. For this talk, we will introduce a few of these techniques as well as apply them to some example problems from past mathematical Olympiads.
