I have a 2D path made up of three points B, C and D. I would like to extrapolate the position of A. The angle on the path at point B must equal to angle at point C and the distance between C and B must be the same as the distance between B and A.
I can work it out using trigonometry in specific situations but when I give my function arbitrary point I get all sorts of anomalies. I can’t figure out a solution that works 100% of the time.
Is their an elegant solution for this type of problem? Yes I’ve tried google but I haven’t found anything helpful.
Thanks for reading
