How many sides has a circle got? ?

Two!!! Inside and Outside.  Ha!!! Ha!!! Ha!!!

A theoretical circle or if you tried to draw a circle? It's impossible to draw a perfect circle, because the smaller you get, the less imprecise the line becomes, so at some point you'll have countable "sides". Theoretically the answer can either be 2 or infinite, zero or one. It's 2 if it's just a line, 

Two Sides and one Center.

A circle is an infinitely long line. There are only two sides of any line. Therefore the Circle has only TWO sides. Philosophically, the two sides represent what is contained within the circle (One Side) and what is contained outside the circle (Second Side).

Sides? 2, inside and outside.

Maybe a 3rd, the curved side.

Just thinking 'outside the box', or in this case, outside the circle.

How many 'line segments', none.

If you think of a quadrilateral as a closed figure having four line segments as sides, and a triangle as a closed figure having three line segments as sides, then a circle has zero line segments as sides.

two. An inside and an outside

A circle doesn't have sides. You are making what's known as a "category error," assigning a circle to the set of things that have sides.

It's like asking, "Which are the sweetest forks?" or "Which is the sharpest apple?"
