Question

Pythagoras triple
Fs#:fscnekk

Answer 1

Answer:

If n is a number, then 2n, n^2-1 and n^2 + 1 are Pythagoras triplets.

Take for example n=2, then 2n=4, n^2-2=3 and n^2+1=5

So 4,3 and 5 are Pythagoras triplets.

These three numbers have another property:

5^2=3^2+4^2 called Pythagoras theorem

They form a right angle triangle
