In the previous math article, we have shown that there are infinitely many Pythagorean triples. In this article, we are going to discuss a very short but effective strategy in generating Pythagorean Triples.

A Pythagorean triple is the integer triple satisfying the Pythagorean equation .

Observe the Pythagorean triples and . We can see that the hypotenuse is greater than the longer side by . From the pattern, we can form the Pythagorean triples satisfying the equation .

Solving the equation we have , which implies that . Now, is always odd (can you see why?). It follows that in order for to be an integer, must be a perfect square. This means, that we are sure that is an integer, if is an odd perfect square.

From here, we can generate infinitely many examples of Pythagorean triples. For example, is an odd perfect square. So plugging it in the equation we have, , then, we have the triple , another Pythagorean Triple. If we let , then we have the triple .

Now, we found another way to generate Pythagorean Triples.
