Abstract

In this paper, we prove Pascal's hexagon theorem by elementary tools only. We follow the well-known route to prove the theorem by Bezóut's theorem, explaining all the details in elementary argument. In particular, we prove a toy version of Study's lemma.

Acknowledgement

We would like to thank the referee for a suggestion to clarify the argument to show the identity (2.1). This led us to devise an even simpler way which does not rely on the matrix argument in the earlier version.
