Inversive Geometry
Part 2: Concyclic Points, Tangents, the Riemann Sphere, and Rings of Four Circles
by JAIME RANGEL-MONDRAGÓN
ABSTRACT: This series of articles showcases a variety of applications around the theme of inversion, which constitutes a strategic way of manipulating configurations of circles and lines in the plane. This article includes the Riemann sphere, rings of four tangent circles, and inverting the Sierpinski sieve.
