Abstract: Let M be an orientable hyperbolic surface without boundary and let c be a closed geodesic in M.
We prove that any side of any triangle formed by distinct lifts of c in the hyperbolic plane is shorter than c.
The talk will be presented for advanced undergraduate and beginning graduate students.
