  The Three Gap Theorem states that there are at most three distinct lengths of
gaps if one places $n$ points on a circle, at angles of $z, 2z, 3z, \ldots nz$
from the starting point. The theorem was first proven in 1958 by S\'os and many
proofs have been found since then. In this note we show how the Three Gap
Theorem can easily be deduced by using Rauzy-Veech induction.
