More about Pythagorean triplets We have seen one way of writing Pythagorean triplets as 2m, m2 - 1, m2 + 1. A Pythagorean triplet a, b, c means a2 + b2 = c2. If we use two natural numbers m and nim. > n), and take a = m2 - n2, b = 2mn, c = m2 + n2, then we can see that c2 = a2 + b2. Thus for different values of m and n with m > n we can generate natural numbers a, b, c such that they form Pythagorean triplets. For example: Take, m = 2, n = 1. Then, a = m2 - n2 = 3, b = 2mn = 4, c = m2 + n2 = 5, is a Pythagorean triplet. (Check it !) For, m = 3, n = 2, we get a = 5, b = 12, c = 13 which is again a Pythagorean triplet. Take some more values for m and nand generate more such triplets.
