The document is a compilation of properties of Pythagorean triplets. It defines key terms like Pythagorean triplet, primitive Pythagorean triplet, hypotenuse number, and aspect ratio. It describes methods for generating triplets from pairs of integers and finding the generators of a triplet. Relations between the elements and properties of the hypotenuse, adjacent sides, and aspect ratios are covered. The document also provides a table of all triplets with a hypotenuse up to 1000.
![6.5 A PHN yields only one PT, and that is always a PPT.
6.6 A non-PHN may yield more than one PTs, and some of them may be PPT.
7. DETERMINING THE NUMBER OF TRIPLETS FOR A GIVEN HYPOTENUSE NUMBER
7.1 A HN may be resolved into its prime factors (and their powers). Not
all prime factors may be HNs. If A is a HN then the general form of
it's prime factorisation is:
A = [p1^a1.p2^a2.p3^a3....pm^am][q1^b1.q2^b2.q3^b3....qn^an]
where all p and q are the prime factors of A, of which the p(s) are
HNs and the q(s) are non-HNs. In other words, all p(s) are of the
form 2a - 1.
7.2 The number of PTs having any HN A as the hypotenuse is given by the
expression:
{(2a1+1)(2a2+1)(2a3+1).........(2am+1) - 1}/2
7.3 If all the prime factors of A are HNs of the form 4a + 1, (i.e. there
are no prime factors of the q type), then some of the PTs of section
7.2 are primitive. The total number of PPTs is given by the
expression:
2^(m - 1)
8. ASPECT RATIO RELATIONS
8.1 If (ABC} is a PPT whose AR is T, then there exist another PPT with
an AR less than T (however small T may be). One such PPT can be
found as under:
Let X = C + 1 if C is even
Or X = C + 2 if C is odd
Then A' = (X^2 + 1)/2
B' = (X^2 - 1)/2 C'
= X
{A'B'C'} is the required PT. If it is not a PPT, scale it down to
its primitive form.
8.2 If {ABC} is a PPT whose AR is T, then there exist another PPT with an
AR greater than T (however large T may be). One such PPT can be found
as under:
Let A' = 3A + 2B + 2C
B' = 2A + 2B + C
C' = 2A + B + 2C
{A'B'C'} is the required PT. If it is not a PPT, scale it down to
its primitive form.
8.3 If {A1B1C1} and {A2B2C2} are two PPTs whose ARs are T1
and T2 respectively then there exist another PPT whose AR lies between
T1 and T2 (however close T1 and T2 may be to each other). One such PPT
can be found as under:
If (A1 + B1) is not a perfect square then scale up {A1B1C1} by a factor
of 2. (i.e. multiply A1,B1 and C1, by 2 and let these be now considered
A1,B1 and C1). Do likewise with {A2B2C2}
Let W = Sqrt(A1 + B1)](https://image.slidesharecdn.com/pythagoreantriplets-100323185409-phpapp02/85/Pythagorean-Triplets-4-320.jpg)

ABBREVIATIONS: AR Aspect Ratio (C/B) (2.3) HN Hypotenuse Number (2.6) PHN Prime Hypotenuse Number (2.7) PPT Primitive Pythagorean Triplet (2.4) PT Pythagorean Triplet (2.1) 2. DEFINITIONS: 2.1 A Pythagorean Triplet (PT) is a set of three positive, non-zero integers, A, B and C such that A^2 = B^2 + C^2. (Equation A). Geometrically this represents a right-angled triangle with A as the hypotenuse, and B and C the sides adjacent to the right angle. A PT is designated henceforth as {ABC} 2.2 To avoid unnecessary duplication, it is considered that B > C. 2.3 The ratio of C/B is termed the Aspect Ratio (AR) of the PT. Its values lies between 0 and 1. 2.4 If {ABC} do not have any common factors, then the PT is said to be a Primitive Pythagorean Triplet (PPT). 2.5 If {ABC} have common factors, then dividing A, B and C by one of the common factors will yield a scaled-down PT. If they are divided by the highest common factor the resulting PT will be a fully scaled-down PT, i.e. a PPT. Similarly, if A, B and C are all multiplied by a common multiplier, it will yield a scaled-up PT which is necessarily non-PPT. 2.6 A Hypotenuse Number (HN) is an integer that can take the value of A in any PT. (Not all integers are HNs. Some of the integers that are HNs are: 5, 10, 13, 15, 17, 20, 25, 26, 29, .... etc). 2.7 If a HN is also a prime number the the HN is termed as a Prime Hypotenuse Number (PHN). (Examples are: 5, 13, 17, 29, ...etc). 3. TRIPLET GENERATORS:
- 2. 3.1 A pair of distinct integers generate a unique PT. Let P and Q be two integers of which P > Q Let U = P^2 + Q^2 Let V = P^2 - Q^2 Let W = 2*P*Q Then P and Q generate a unique PT {ABC} given by setting A = U B = larger of V and W C = smaller of V and W 3.2 If {ABC} is a PT then its generators P and Q can be found as under: Let W = A + B 3.2.1 If W is a perfect square then P = Sqrt((A + C)/2) and Q = Sqrt((A - C)/2) 3.2.2 If W is not a perfect square then P = Sqrt((A + B)/2) and Q = Sqrt((A - B)/2) 3.3 If P-Q is equal to one, then A-B is also equal to one. 3.4 In general, if P-Q is equal to j, then the difference between the hypotenuse (A) and one of the adjacent sides (either B or C) is equal to j^2. In other words, either A-B or A-C is equal to j^2. 3.4.1 The value of j/P determines the above. If j/P is less than (2 - sqrt*2) then (A - B) = j^2 If j/P is greater than (2 - sqrt*2) then (A - C) = j^2 3.5 If P and Q are relatively prime to each other and of opposite odd- even parity then they generate a PPT. 4. SOME TRIPLET ELEMENTS RELATIONS: If A,B and C are the elements of a PT then: 4.1 If B or C is added to A then one results in a perfect square, and the other in twice a perfect square. 4.2 If B or C is subtracted from A then one results in a perfect square, and the other in twice a perfect square. 4.3 At least one element of any PT is divisible by 3, and one by 4, and one by 5. 4.4 The product of the two adjacent sides is always divisible by 12. 4.5 The product of all three sides is always divisible by 60. 5. ADJACENT SIDES: 5.1 Whereas all integers cannot be the hypotenuse of a PT, all integers, except 1 and 2 can be the adjacent side of a PT. 5.2 If G be any integer greater than 2, and designating any one adjacent side of a PT (i.e. either B or C). At least one other integer can be found that will form the other adjacent side of a PT. This can be done as under: 5.2.1 If G is odd: Resolve G into any two factors - say v and w, where v > w. If G is a prime number then v = G and w = 1. Let P
- 3. = (v + w)/2 and Q = (v-w)/2. Then P and Q are the generators of the required PT. (See Sec 3.) If v and w are chosen prime to each other, then it yields a PPT. 5.2.2 If G is even: Let G = 2PQ, where P and Q may be any 2 integers, P > Q. Then P and Q are the generators of the required PT. (See Sec 3.) If G is even but not divisible by 4, then no primitive solution can exist. If G is divisible by 4 then choose P and Q relatively prime to each other, and of unlike odd-even parity, to obtain a PPT. 5.3 Since G can be resolved as above in may be more than one ways, G may be an adjacent side in more than one PT. 5.4 To find the number of PTs in which G is one adjacent side: Resolve G into its prime factors, (and their powers). In general the resolution can be expressed as under: G = p1^m1.p2^m2.p3^m3..........pr^mr where p1,p2,p3....pr are all prime numbers, and m1,m2,m3....mr are their respective powers. 5.5 The number of primitive triplets in which G can be an adjacent side is given by: 2^(r-1). Except when G is an even number not divisible by 4, in which case no primitive solutions are possible 5.6 The total number of triplets (prime or otherwise) in which G can be an adjacent side is given by: 5.6.1 If G is odd: All the prime factors (p1 to pr) are odd, and the number of triplets is given by: {(2.a1+1)(2.a2+1)(2.a3+1)....(2ar+1) - 1}/2 5.6.2 If G is even: All the prime factors except one, are odd. The only even prime factor is 2. Let p1=2 and a1 be the power of p1. All other prime factors (p2 to pr) are odd, and the number of triplets is given by: {(2.a1- 1)(2.a2+1)(2.a3+1)....(2ar+1) - 1}/2 (note the -ve sign in the first term of this as against +ve sign in the expression above for odd G. All other signs are +ve in both cases) 5.7 Query: In how many of the above triplets is G the bigger adjacent side? 6. SOME PROPERTIES OF THE HYPOTENUSE 6.1 A HN can always be expressed as the sum of two squares (or a multiple of the sum of two squares. Conversely, any number that can be expressed as a sum of two squares (or a multiple thereof) is a HN. The two numbers in question are the generators of a PT. (see section 3.) 6.2 A HN may be expressed as above in more than one ways. In such cases the HN may yield as many PT as the number of ways it can be so expressed. 6.3 A PHN can always be expressed in the form 4a + 1. Conversely, all prime numbers of the form 4a + 1 are HNs. 6.4 All HN have at least one prime factor of the form 4a + 1.
- 4. 6.5 A PHN yields only one PT, and that is always a PPT. 6.6 A non-PHN may yield more than one PTs, and some of them may be PPT. 7. DETERMINING THE NUMBER OF TRIPLETS FOR A GIVEN HYPOTENUSE NUMBER 7.1 A HN may be resolved into its prime factors (and their powers). Not all prime factors may be HNs. If A is a HN then the general form of it's prime factorisation is: A = [p1^a1.p2^a2.p3^a3....pm^am][q1^b1.q2^b2.q3^b3....qn^an] where all p and q are the prime factors of A, of which the p(s) are HNs and the q(s) are non-HNs. In other words, all p(s) are of the form 2a - 1. 7.2 The number of PTs having any HN A as the hypotenuse is given by the expression: {(2a1+1)(2a2+1)(2a3+1).........(2am+1) - 1}/2 7.3 If all the prime factors of A are HNs of the form 4a + 1, (i.e. there are no prime factors of the q type), then some of the PTs of section 7.2 are primitive. The total number of PPTs is given by the expression: 2^(m - 1) 8. ASPECT RATIO RELATIONS 8.1 If (ABC} is a PPT whose AR is T, then there exist another PPT with an AR less than T (however small T may be). One such PPT can be found as under: Let X = C + 1 if C is even Or X = C + 2 if C is odd Then A' = (X^2 + 1)/2 B' = (X^2 - 1)/2 C' = X {A'B'C'} is the required PT. If it is not a PPT, scale it down to its primitive form. 8.2 If {ABC} is a PPT whose AR is T, then there exist another PPT with an AR greater than T (however large T may be). One such PPT can be found as under: Let A' = 3A + 2B + 2C B' = 2A + 2B + C C' = 2A + B + 2C {A'B'C'} is the required PT. If it is not a PPT, scale it down to its primitive form. 8.3 If {A1B1C1} and {A2B2C2} are two PPTs whose ARs are T1 and T2 respectively then there exist another PPT whose AR lies between T1 and T2 (however close T1 and T2 may be to each other). One such PPT can be found as under: If (A1 + B1) is not a perfect square then scale up {A1B1C1} by a factor of 2. (i.e. multiply A1,B1 and C1, by 2 and let these be now considered A1,B1 and C1). Do likewise with {A2B2C2} Let W = Sqrt(A1 + B1)
- 5. X = Sqrt(A1 - B1) Y = Sqrt(A2 + B2) Z = Sqrt(A2 - B2) Then A' = A1 + A2 + WY + XZ B' = B1 + B2 + WY - XZ C' = C1 + C2 + XY + WZ {A'B'C'} is the required PT.
