Having a brain fart here - best way to get the tangent vectors on both sides of a G0 continuous “kink” in a curve? Easy enough if it’s a polyline or the equivalent, but what if not?

I can think of a couple of ways - one, rather convoluted, is to get all the params of the kinks with their tangent vectors, then reverse the curve and do it again, then match up the joints and get the vector angle between… Or just split up the curve at the kinks and work with the segments… just seems like there should be a less complicated way.
