Pythagorean Triples
PYTHAGOREAN TRIPLES
MONDAY, OCTOBER 11, 2010
According to the website link,
www.math.uic.edu/~fields/puzzle/triples.html, there is a formula that
can find all pythagorean triples--n2 - m2, 2mn, and n2 + m2
(www.math.uic.edu. All pythagorean triples follow the a2 + b2 = c2.
Wolfram MathWorld gives their definition of a pythagorean triple as "a
triple of positive integers a, b, and c such that a right triangle
exists with legs a, b, and hypotenuse c (mathworld.wolfram.com). It is
also equivalent to finding positive integers a, b, and c that satisfy
a^2+b^2=c^2 (www.math.uic.edu).
The website, www.cut-the-knot.org/pythagoras/pythTriple.shtml, gives
proof of the three number a, b, and c that always form a Pythagorean
triple:
(n2 - m2)2 + (2mn)2 = n4 - 2n2m2 + m4 + 4n2m2
= n4 + 2n2m2 + m4
= (n2 + m2)2 (www.cut-the-knot.org).
