"A circle (in the plane) is usually defined as a curve such that its points all have the same distance from a given point" — a bit problematic; say, half a circle, is it also a circle? It IS "a curve such that its points all have the same distance from a given point", isn't it? [[User:Boris Tsirelson|Boris Tsirelson]] 10:05, 2 February 2010 (UTC) | |||
