   To calculate a Pythagorean triple, take any term of this sequence and convert it to an improper fraction (for mixed number , the corresponding improper fraction is ). Then its numerator and denominator are the sides, b and a, of a right triangle, and the hypotenuse is b + 1. For example:

4. Pythagorean triple - Wikipedia

   Animation demonstrating the smallest Pythagorean triple, 3 2 + 4 2 = 5 2. A Pythagorean triple consists of three positive integers a, b, and c, such that a 2 + b 2 = c 2. Such a triple is commonly written (a, b, c), a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k.

5. Tree of primitive Pythagorean triples - Wikipedia

   en.wikipedia.org/wiki/Tree_of_primitive...

   This approach relies on the standard formula for generating any primitive Pythagorean triple from a half-angle tangent. Specifically one writes t = n / m = b / (a + c), where t is the tangent of half of the interior angle that is opposite to the side of length b. The root node of the tree is t = 1/2, which is for the primitive Pythagorean ...
