We give various methods of finding the geodesics on surfaces, before finally making contact with the idea of shortest paths towards the end

How Much Does a Curve Curve?,curve is not contained in a straight line (so that straight lines have zero curvature), and the torsion measures the extent to which a curve is not contained in a plane (so that plane curves have zero torsion). It turns out that the curvature and torsion together determine the shape of a curve.
