We consider some new properties of simple plane curves. Starting from a unusual (and metric) formulation of the tangent line, we prove that at every point of a plane curve there is at least a tangent direction. So, from a pure theoretical point of vue, it is possible to have many tangent directions at every point of a plane curve.

Abstract
We consider some new properties of simple plane curves. Starting from a unusual (and metric) formulation of the tangent line, we prove that at every point of a plane curve there is at least a tangent direction. So, from a pure theoretical point of vue, it is possible to have many tangent directions at every point of a plane curve.File in questo prodotto:
