What is a Pythagorean Triplet?

 Pythagorean triplets

Numbers that follow the Pythagoras theorem are called Pythagorean triplets

Three numbers a, b  and c form a Pythagorean triplet if:

$a^2+b^2=c^2$

Example: 3,4 and 5

12, 5, 13 and so on

$3^2+4^2=5^2$

$9 + 16 = 25$.

So, the numbers 3, 4, 5 form a Pythagorean triplet.
