Title: What are Ceva's and Menelaus's Theorems?
Speaker: Charles Baker, The Ohio State University
Seminar Type: What is... ?
Abstract: In this talk, we will discuss Ceva's and Menelaus's Theorems (of triangular geometry), which discuss respectively when lines going through vertices of a triangle are concurrent (have a triple intersection), and the condition for points on the sides of a triangle to be collinear.
We will discuss the proofs, discuss some quick applications, and then (time permitting) will unify the theorems using projective geometry.
