Does a circle have 1 side, or is it no sides?



Answers:
There are two sources of ambiguity here.

The word CIRCLE sometimes refers to a circular disk (because it is common to talk about "the area of a circle"), but often the word refers only to the boundary of the disk (namely, the points that are equally distant from the point at the center of the figure).

The meaning of the word SIDE depends on its context. A polygon in the plane has, by definition, n vertices and each pair of consecutive vertices are joined by a side. It is clear that a polygon with n vertices has n sides. In general, the word side depends on the dimension of the figure -- a side is always part of the boundary. So what is the side of a circle? If you think of the circle as a disk then it it has an up-side and a down-side. If you think of it as a curve, then it has an inside and an outside. If you think of it as the limit of an n-sided regular polygon, then one can justify the answer that the circle has infinitely many infinitesimal sides. :

the question, "How many sides does a circle have?", is too ambiguous to have a definite answer.
it has a circumference not sides
Two - an inside and an outside.
circle is a circle with no sides
i hope not
an infinite number of sides.
A circle doesnt have sides. It has a circumference. And even if it did have sides, it would have an infinite amount of sides. Because a cirlce is round.
In order to have a side, you first need to have an angle.
A circle has no sides, because it has no angles.
Four sides.
1. Inside
2. Outside
3. Frontside
4. Backside
5. Am I allowed to say backside here, because they won't let me say ****?
it has an INside. haha
I don't think it has a side, as such. more like a perimeter.
I think of a circle as a regular polygon with an infinite number of sides, but I suppose that is just me.
only if you split it in two. then it wouldnt be a circle now would it?
no sides it is called a cicumference.
You can be inside the circle, or outside the circle.
id say it has no sides, it is one continuous line
its a pretty ambigous question but a maths geek would tell you when you get down to in really small detail it is made up of such a large number of straight lines (but really really small) that the number is infinate as it is beyond comprehension. ergo an infinate number of sides

A circle has an infinite number of sides. :o)
Try an infinite number of sides.
It has no sides, just the circumference.
It has a circumference
It has an infinite number of sides.
Look at regular polygons, the more sides they have the more they look like a circle.
it has one side
