A Pythagorean triple is a triple of positive integers a, b, and c such that a right triangle exists with legs a, b, and hypotenuse c (Bluman, 2005). A Pythagorean triple is a triple of positive integers (a, b, c) where a2 + b2 = c2. A triple is simply a right triangle whose sides are positive integers. An easy way to generate Pythagorean triples is to multiply any known Pythagorean triple by an integer (any integer) (Vargas, 2008). In project #4, pg. 522, (Mathematics in Our World) introduced some new information to add to my mathematics knowledge of numbers. The numbers 3, 4, and 5 are called Pythagorean triples since 32 + 42 = 52. The numbers 5, 12, and 13 are also Pythagorean triples since 52 + 122 = 132. Can you find any other Pythagorean triples? Actually, there is a set of formulas that will generate an infinite number of Pythagorean triples and write a brief report on the subject (Bluman, 2005). When asked to find any other Pythagorean triples, I found 5, choosing 2 integers, m and n, with m less than n (Manuel, 2010). Three formulas I choose to form the Pythagorean triple, which can be calculated from: n2 – m2

2mn

n2 + m2 (Manuel, 2010).

1) m=3, n=4

n2– m2=(4)2–(3)2=16-9=7VERIFICATION: (7)2+(24)2=(25)2 2mn=2(3)(4)=2449+576=625

n2+m2=(4)2+(3)2=16+9=25625=625

TRIPLE: 7, 24, 2

2) m=1, n=3

n2-m2=(3)2-(1)2=9-1=8

2mn=2(1)(3)=6

n2+m2=(3)2+(1)2=9+1=10

TRIPLE: 6,8,10

VERIFICATION: (6)2+(8)2=(10)2

36+64=100

100=100

3) m=4, n=5

n2-m2=(5)2=(4)2=25-16=9

2mn=2(4)(5)=40

n2+m2=(5)2+(4)2=25+16=41

TRIPLE: 9,40,41

VERIFICATION: (9)2=(40)2=(41)2

1681=1681

4) m=5, n=6

n2-m2=(6)2-(5)2=36-25=11

2mn=2(5)(6)=60

n2+m2=(6)2+(5)2=36+25=61

TRIPLE: 11,,60,61

VERIFICATION: (11)2=(60)2=(61)2
