Pythagoras

So we all know that to find the length of a hypotenuse you use the formula A squared + B squared = C squared.  What happens, however, if A and B = 1 ?  Did Pythagoras note this problem?  Is 2 the only number with an infinite decimal for a square root?  How do you find the length of the hypotenuse in this situation?

Yes, four examples was given, and then a rule. Clearly, the rule wasn't derived from the examples, so no generalization.
However, no one mentioned generalization. The phrases used were 'more specifically' (>>4) vs. 'more in general'(>>6).
I stand by my claim (me being >>6 and >>11) that a general rule is more general that 4 specific examples. That is my claim, and the whole of my claim.

This thread was over at >>5.
This is an entirely recreational (read: pointless) semantics nitpick, and would have been gone now if you people would stop bumping it.
