It's much easier to work with c2 = a2 +b2 when you're looking for the values of a or b than using the radical form you propose. Also, when you throw in the Law of Cosines, c2 = a2 + b2 - 2abCos(C), it's nice to have both formulas follow the same pattern.
1+1=2: 2 = c2. Swap sides: c2 = 2. Square root of both sides: c = √2. Which is about: c = 1.4142... It works the other way around, too: when the three sides of a triangle make a2 + b2 = c2, then the triangle is right angled.
We can compute the results using a 2 + b 2 + c 2 = distance 2 version of the theorem. As we suspected, there’s a large gap between the Tough and Sensitive Guy, with Average Joe in the middle. The theorem helps us quantify this distance and do interesting things like cluster similar results.
7 gru 2016 · As the figure shows, the distance formula is simply the Pythagorean Theorem (a2 + b2 = c2) solved for the hypotenuse: Take another look at the figure. The legs of the right triangle ( a and b under the square root symbol) have lengths equal to ( x2 – x1) and ( y2 – y1 ).

""Pythagorean triples" are integer solutions to the Pythagorean Theorem, a2 + b2 = c2. I like "triplets," but "triples" seems to be the favored term. For a right triangle, the c side is the hypotenuse, the side opposite the right angle." Example: 3^2 + 4^2 = 5^2
