# Can a circle be a straight line?

Posted by: reece

• Yes, it's possible because...

• No, it's impossible because..

• no matter what a circle is a bent line, you cannot stack straight lines and get a circle, stacking bent lines may though.

• A circle can not be turned into a straight line the line is curved and can't be straight

• lol triangle.128k, that is silly, it may look like a line but it is still a circle. Plus, if the shape was a sphere from all viewpoints it will look like a circle.

• Mathematics has the answer to this one. A circle is defined as being a shape with points that are all equidistant to a fixed point, called a point. A line can be defined as slope 0, but clearly, the slope isn't 0 at any point. If we grab a straight line, find a fixed point, we can clearly see that all points aren't equidistant to the fixed point. Another idea is that a line is like a double ray, with two points being stretched off in 2 directions in 1 dimension infinitely. Since a circle is 2 dimensional, it can't be considered a line as a line is one dimensional.

Yes, you can. However, just because I know this question is widely used in colleges for Geometry, Theoretical astronautical propulsion Research Engineering, and theoretical physics classes, you'll need to provide details defining what your line is, what it is made of, and length of line so I can assure I am not answering those questions.

I was hinting at topology ;)

Ah, How about this: using a straight object to create an impression in a malleable surface, continue pushing and eventually the malleable substance will completely wrap around, encasing the straight object within the now spherical object, essentially making the straight object a sphere / circle.

If one drives in a straight line, one would eventually end at the point he started, effectively creating a circle...From a straight line. Creative thinking FTW.
