Question

Which of the following is pythagorean triplet?

• A. 3 ,4 ,5
• B. 5 ,12 ,13
• C. 7 ,24 ,25
• D. All of these

Answer 1

The correct option is D All of these

$a,b$ and $c$ are called pythagorean triplet if $a^2+b^2=c^2$

Clearly, $3^2+4^2=9+16=25=5^2$

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

$7^2+{24}^2=49+576=625={25}^2$

All three of the given options are pythagorean triplet.
