FWIW, if anyone cares, I just posted the html version of this article to my web site. http://home.pipeline.com/~hbaker1/FAQ-circumcircle.htm Hopefully, it is more readable than the ascii version. Note very carefully: due to the "head-to-tail" orientation of the vectors, the various vector products have surprising signs; e.g., a.b = -|a||b| cos C Of course, even with traditional vectors, this is still true, but it looks really weird, and can easily trip you (& me!) up.
