You can calculate the values of the angles yourself, if you like. I think you already did, actually ;)

Yes, that applet did. The result was NaN which means not a number(undefined). The fact that one can play games and define a new geometry is not a secret. But people tend to have agreed upon foundations from which to proceed in debates. So in closing my participation in this greased pig contest I will give a few links to definitions.

Unit Vectors

Unit Vectors:

• Vectors that indicate Direction Only.
• The Length of a Unit Vector is always equal to One.

Triangle -- from Mathworld

Allowable side lengths a, b, and c for a triangle are given by the set of inequalities a > 0, b > 0, c > 0, and , , .

Degenerate --- from Mathworld

A limiting case in which a class of object changes its nature so as to belong to another, usually simpler, class. For example, the point is a degenerate case of the circle as the radius approaches 0

Pssst. Go back and look at my post 955 and read the little text again - your definition from Mathworld isn't telling me anything I don't already know....

Go easy, FRiend - as heartlander pointed out, this thread "degenerated" some time ago, so it's all in good fun. No need to get ulcers over triangular circles, I say ;)

IOW, you yourself said that square circles are "foolishness" - don't go getting all serious on me now ;)
