Finding the center of a circumcircle?


Suppose I have a circumcircle - so that for example it appears in the construction text window as "Circumcircle(A,B,C)". Is there a way to get that point that is its center without constructing it? — Dave

I mean, create it as a construction element (I forget what its called, but you know: a real point like I get by using the point tool and clicking, except this would be a dependent point).

I know how to construct it from the perpendicular bisectors of the chords formed by the 3 points - it occurs to me that maybe this is the kind of thing you can do if you can use macros - is that the case?

Thanks! — Dave

Dave,

probably Center is the mode you are looking for...

What exactly do you mean by "get this point"?
