Steiner's Porism: An Activity Using the TI-92.
Beem, Paul
Steiner's Porism states that if you can draw a connected ring of circles in the annular region between two original circles, the ring will be successfully completed no matter where you start. This paper explores how the TI-92 graphing calculator can be used to demonstrate Steiner's Porism and illustrate the main points of its proof. Inversion in the plane is used to prove theorems and generate the connected ring of circles in a given annular region. (KHR)
