There are various formulas that will generate Pythagorean triples. Use the specified formula and specified values to generate a Pythagorean triple.For positive integers r and s such that r > s, the following set of equations will generate a Pythagorean triple (a, b, c). a = r2 - s2, b = 2rs, c = r2 + s2.Use this method with the values r = 8 and s = 1 to generate a Pythagorean triple.
