A polyline is a bunch of lines stuck together end to end. I assumed that AI was creating curves by calculating the individual slopes of a curve cut into sections (taking the derivative of each tiny curve, although my calculus is a little rusty). More resolution was gained by dividing the curve into more pieces. As the length limit went to zero, a better approximation of a curve would result. I don't think it is possible to create a perfect ellipse (of which a circle is a special case) this way, but you can get close. I understand from you that they are not done this way in AI, but use Bezier curves instead. Obviously you are right; all you have to do is look at the AI curve and see the handles and end points. My mistake.

Who said that definitions and manipulations were mutually exclusive topics in a conversation? That is kooky talk. They are tightly tied together.

Mostly, I don't really know what you are talking about here, although I think we agree that AI's arc/ellipse tool is unusable. All I'm asking is that I be able to control circles and arcs via their salient features. I couldn't care less what happens "under the hood" as long as my output data are accurate within a given error range. Thanks, for putting me straight about the polylines, though!
