Question

Are the numbers $12,5$ and $13$ form a Pythagorean Triplet?

Answer 1

When there are three positive integers $a,b,c$ which are related by the equation,

$a^2+b^2=c^2$, then they are said to be a Pythagorean triple.

Now, $5^2+{12}^2=25+144=169={13}^2$

$\therefore$ They are Pythagorean Triple.
