In KleppnerKleppner's "intuitive" explanation of acceleration equations in polar coordinates he useuses a geometric argument based on the figures on the left, but iI don't get how the angles between the velocities are the same as the angle between the position vectors. I find it simple when the curve is a circle, but in the general clase icase I have no idea how to prove it.
