Generating Pythagorean Triples

Updated on September 21, 2012

Generating Pythagorean Triples

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 as (a, b, c) and a well-known example is (3,4,5). Other Pythagorean Triples can be generated by the following process:

Step One : Choose any two positive integers , s and t such that s > t.

Step Two : Let a = s^2 – t^2

b = 2st

c = s^2 + t^2

Exanple One : Let s = 3 amd t = 2

a = 3^2 - 2^2

9 -4 = 5

b = 2(3)(2) = 12

c = 3^2 + 2^2

= 9 + 4 = 13

The Pythagorean Triple generated is 5, 12, 13

Check if they satisfy Pythagorean Theorem :

5^2 + 12^2 = 13^2

25 + 144 = 169

169 = 169

Example Two : Let s = 4 and t = 3

a = 4^2 - 3^2

16 - 9 = 7

b = 2 (4)(3) = 24

c = 4^2 + 3^2

= 16 + 9 = 25

The Pythagorean Triple generated is 7, 24, 25

Check : 7^2 + 24^2 = 25^2

49 + 576 = 625

625 = 625

      The title grabbed my attention. I just had to see what it was about. I'm glad you have other interests that you write about. This one will be for the pythagorean's. They need something interesting to peruse also.
