Generating Pythagorean Triples (Bredenkamp 2013)
Use the sliders to change the values of i (an uneven number) and j (an even number). The construction will generate a pythagorean triple and triangle showing its incircle and other properties. If i and j are relatively prime, the triple will generate a Primitive Pythagorean Triple (PPT).
