Is infinite circle a straight line? Me and my friends have a serious argument about this. What is your opinion?

[Tiara]

Ah, yes, the Nicolas of Cusa (or Infinite Circle) paradox

And yes, it is a straight line

EDIT; I did some searching so you could have an explaination for my answer;

Nicholas of Cusa (1401-1464) made the following interesting point regarding the shape of an infinite circle. The curvature of a circle's circumference decreases as the size of the circle increases. For example, the curvature of the earth's surface is so negligible that it appears flat. The limit of decrease in curvature is a straight line.

An infinite circle is therefore... a straight line!

How does that work? (I don't get along with math.)

EDIT: Oh.

[Tiara]

Read my edit.

i'm not going to explain it all the way. Explaining a paradox sucks ass let's just say that this was an issue we tackled when i was still a student.

Far out man...

I thought a straight line was a circle with infinite radius, not the other way around... or something like that... damn geometry.

An infinite circle must be a straight line, for if it had the slightest bit of curve, it would eventualy come back around and complete the circle, making it no longer infinite.
