# Apollonius Problem: Solution via Vectors (Geometric Algebra)

This worksheet enables students to explore the solution presented in the article "The Problem of Apollonius as an Opportunity for Teaching Students to Use Reflections and Rotations to Solve Geometry Problems via Geometric (Clifford) Algebra" (http://vixra.org/abs/1605.0233). It is part of a series of resources that I am preparing his resource is part of a series that I am preparing in support of Professor David Hestenes's goal of using Geometric Algebra(GA) to integrate high-school algebra,geometry, trigonometry,and physics into a coherent curriculum.
