Idenetify , with reason , which of the following are Pythagorean triplets :
`(4,9,12) `

Explanation

`4^(2) = 16 , 9^(2) = 81, 12^(2) = 144`
` therefore 4^(2) + 9^(2) = 16+ 81 = 97`
` therefore 4^(2) + 9^(2) ne 12^(2)`
The square of the largest number is not equal to
the sum of the squares of the others two numbers .
` therefore (4,9,12)` is not a Pythagorean triplet
