Thats a funny triangle with lengths 1,1,2 !!!

Technically a line, but it IS the correct solution to the posed problem 🙂

I don't understand this entire thread. 😕
By a2 do you mean a^2?
If so, why isn't c = sqrt(2) ?

Actually, I think the theorem goes....." in any right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides"

The full formula from which the Pythagorus Theorem is based is as follows (as I recall)

C^2 = A^2 + B^2 - 2*A*B*cos(o) (where o = the angle between sides A and B)

At 90 degrees, cos(o) = 0, thus eliminating the third term.

At 180 degrees, cos(o) = -1, making the formula C^2 = A^2 + B^2 + 2*A*B, which simplifies into C^2 = (A+B)^2. Given lengths are generally considered positive, C is thus A+B.

Pythagoras pretty much predates cos.
