| Jun 18, 2010 at 18:18 | comment | added | Ryan Budney | Ah, sorry. Somehow I completely mis-read your answer. It makes sense now and my comments were off-track. | |
| Jun 18, 2010 at 18:11 | comment | added | Ryan Budney | I mean, do all the circles have the same radius? Certainly their centres and axis can vary. | |
| Jun 18, 2010 at 17:58 | comment | added | Joseph O'Rourke | @Ryan: Yes. "A geometric circle in $R^3$ is the set of points in a fixed plane that lie a fixed positive distance from a center point that lies in the same plane." | |
