One equation satisfying a Pythagorean Triplet
A, B, C is Given A is
odd, then
B = (A2 - 1)/2
C = (A2 + 1)/2
Another equation derived by Plato was
(m2+1)2
= (m2-1)2 + (2m)2
where m is a natural number. The above equation
is called Plato's Formula.
Euclid has also another method, namely:
Given integers x and y,
A = x2 - y2
B = 2xy
C = x2 + y2
