How do I track player motions and award points based on angl

I have a player object that is able to move in different ways, circles, ellipses, acute and obtuse angles. I had an idea where when the player object makes a 90 degree turn or another pre-set angle, that the I could write some detection in that notices a right angle movement path has been created, and awards points.

Not sure if this is possible or feasible, but Im curious none the less!

Solved this, using tiny grid of sprites, a counter and a math function that measured the angle between sprites that had spawned another invisible sprite upon detection.
