Are you looking for code on how to draw a circular arc?

These are my thoughts but please consult an elementary book on geometry: The geometric notion is a measurement of the turn. If you have a tangent vector v1 at point A, and then move infinitesimally, and that same tangent vector changed to v2, the amount of turn can be measured by cross product of these two vectors which by some complex algebra will turn to formulas you find in various textbooks.
