The following table summarizes the values for powers of 10. , the number of triples with hypotenuse be denoted Let the number of triples with hypotenuse be denoted There are 50 Pythagorean triples with hypotenuse less than 100, the first few of which, sorted by increasing, are (3, 4, 5), In addition, one side of every Pythagorean triple is divisible by 3, another by 4, and another by 5. For primitive solutions, one of or must be even,Īnd the other odd (Shanks 1993, p. 141), with
The radial lines corresponding to imprimitive triples in the original plot are absent The primitive triples are illustrated above, and it can be seen immediately that
Prime, since other solutions can be generated trivially from the primitive ones. It is usual to consider only primitive Pythagorean triples (also called "reduced"triples) in which and are relatively
Similarly, plots of points in the -plane suchĪre shown above for successively larger bounds. Triple are shown above for successively larger bounds. The right triangle having these side lengths is The smallest and best-known Pythagorean triple is.
