Idenetify , with reason , which of the following are Pythagorean triplets :

Explanation

`3^(2) = 9,5^(2) = 25, 4^(2) = 16`
`therefore 3^(2) + 4^(2) = 9+ 16 = 25`
` therefore 3^(2) + 4^(2) = 5^(2)`
The square of the largest number is equal to the
sum of the squares of the other two number
` therefore ` (3,5,4) is a Pythagorean triplet .
