The segment endpoints can be constrained such that adjacent control points are tangent or symmetric to the segments at the endpoint. First, start editing the curve, then pick one of the tools and then pick a point. Click again on the tool to deactivate it, so you can move the point.
 * remove constraints on the points so the curve can have sharp corners.
 * force adjacent control points to be tangent.
 * force adjacent control points to be tangent and equidistant.
