Are you allowing the concept of infinity?

Your riddles are usually very vague. I'm assuming you're referring to a circle (a twodimensional shape) that exists in Euclidean geometry. If that is the case, I insist that axiomatically define "side" before this riddle could be answered.

If this is the solution, the riddle should ask how many "regions" there are in a circle.
A circle has infinitely many "sides." Circle  infinite sides
