In this paper we construct an affine model of a Riemann surface with a flatRiemannian metric associated to a Schwarz-Christoffel mapping of the upper halfplane onto a rational triangle. We explain the relation between the geodesicson this Riemann surface and billiard motions in a regular stellated $n$-gon inthe complex plane.
