Question

yup

anonymous · Answer

Er.. sometimes? If the center doesn't have a name, you have to use points on the circumference.

I would say you need a center and radius to name a circle

You need a center and radius to *define* a circle, not name it.

turingtest · Answer

well that's where I think the terminology is a bit fuzzy here :/

turingtest · Answer

I would argue that three non-colinear  points define a plane, "naming" it seems trivial...

anonymous · Answer

And really, all that's needed to define a circle is the radius, since placement of coordinate axes is arbitrary.
I would answer 'True' to the above question, but sometimes the center is unknown or isn't given.

anonymous · Answer

We're not talking about naming or defining planes, just naming circles.

As in "hey see all those circles drawn on that page there? Well, I'm talking about 'this' one."
