sum of the square of two smaller sides of a right angled triangle equals square of the third side i.e. hypotenuse.

sum of the square of two rational numbers equals square of the third number. These numbers are called Pythagorean triplets.

Some Interesting Properties of Pythagorean sub-triplets

1. y is always less than n/2 i.e. y<n/2

2.n is always greater than 2. lowest integer value of n cannot be less than 3.

3.For a given y, the smallest value of n of the triplet cannot be less than 2y+1.

4.For a given y, several Pythagorean sub-pairs (n, x) can be found out.

5.The lowest (n,x) pair are such that 3x=3y=n (exception y=8)

6.For y=odd no. , n/y 3,5,7,9,11,... which is an AP with common difference 2.
(exception y=9 where 1st,4th,7th,10th...no. with common difference of 3 are in ratio 5/2,7/2.9/2 for n/y)

7.For y=even no. , n/y 3,4,5,6,7,... which is an AP with common difference 1.
(exception y=8 where 2nd,4th,6th,8th...no.  are in above ratio for n/y and
& 1st,3rd,5th,7th.. ..no. are with  n/y 5/2,7/2,9/2,11/2...with common difference of 1)

8. If y=odd number, [y n x] y= y [y n x] 1 i.e. y times the corresponding value of sub-triplets for 1
except y=9 or odd multiple of 9.For odd multiples of 9, [y n x] 9m= m [y n x] 9 (where m=y/9 & is odd.)

9. If  y is a multiple of 8, [y n x] y=( y/8) [y n x] 8 i.e.( y/8)times the corresponding value of sub-triplets for 8.

10. For  given y, there is a constant difference between consecutive n values. For y=1,2 diff=2; y=4,8 diff=4;
y=3,6,9  diff=6; y=5,10 diff=10 and y=7 diff=14. All differences are of even value.

11.The sub-triplets of "y=an odd integer" are all odd. The sub-triplets of "y=even integer" all even with exception
of y=8 and its odd multiples where x is an odd integer.

12. For each integer value of y, infinite number of triplets can be generated.

13.If a (equals n), b (equals n plus x) are the smaller sides and c (equals n plus x plus y) is the hypotenuse of the right angled triangle in X-Y plane, then  a2+b2=c2.If c (equals n') be the smaller side of another right angled triangle and d (equals n' plus x') is a line along z-axis, then  the consequent triangle  for the same y value exists and (x',n') can be found  provided  n'=x+n+y and x' satisfies  the equation  n'=y'+(2y2+2yx)1/2 and n'=y'+(2y2+2yx)1/2    and  x' is an integer or a rational number.Thus a2+b2+d2=f2 where f=n'+x'+y'.

Analogous Pythagoras Theorem for Hyperbolic right angled triangle

If a, b and c are the three sides of a hyperbolic triangle (right angled) with angle between two small sides a, b being 90° and c is the hypotenuse, then coshc=cosha * coshb; It may be noted that the vertices of the triangle lie in the hyperbolic plane.
