thus: ah, this looks like a good exercise for comprehending "absolute value" function, as well as of the trilateral inequality.
know the tetrahedral version?
> | x - y | >= | |x| - |y| | > means these two things: > | x - y | >= |x| - |y| > | x - y | >= |y| - |x| > both of which are pretty clear from the triangle inequality.
thus: I don't get your notation; are you also referring to the trisectors of the exterior angle of C, the supplement, and are all of the points on the same line, but C?

thus: according to _17 Essays on the Fermat Numbers_ from the SMC, Fermat retracted this conjecture in a letter to Frenecle (sp.?).
> false. Fermat numbers are of the form 2^2^n+1 and the
thus: in Sudan, Iran and possibly all other once and future British quagmires.... Belize, Canada, Trinidad AND Tobago; when we get there, be sure to ask if it's more than one country, and did we miss Trinidad andOR Tobago?
