## What is The Triangle Center?

This is both an interactive book about the "centers" of triangles and a tool for exploring them. How are the centers defined and how are they related to each other? Discover the meaning and usefulness of trilinear and barycentric coordinates. See how those coordinates can be used to solve equations, create color gradients, solve puzzles, and create geometric art.
