Tabulating all Pythagorean triples - Klostergaard (1978)
The construction illustrates a method to generate all Pythagorean triples.
Instructions: Use the slider for n to change its value. The p-slider will pick a divisor d of m . For more information on the background of this construction see article below.
Note that the radius of the incircle is equal to n, and that if d and q are relative prime the triple t will be prime.
