Conway’s Circle Theorem: a proof, this time with words

Back in the olden days, Colin entered a proof without words in the Big Mathoff. It was mentioned, in passing, in a New York Times obituary of John Horton Conway.

Proofs without words are lovely, if your geometry is super-sharp and you can read between the line segments and follow the implicitly-made arguments. This video is for the benefit of those who don’t see it quite so immediately, and goes through the reasoning in more detail.

Colin and Elizabeth discuss a proof without words of the Conway Circle Theorem (only this time using words).
