➡ No 5 , 7 and 9 isn't a Pythagorean triplet because square of 5 is 25 , 7 is 49 and that of 9 is 81 .
When we add square of 5 and 7 , (that is 25 + 49 = 74 ) we get 74 that is not equal to square root of 9 (81) .
Note : According to Pythagorean triplet when the square of two smaller no. is added then they should be equal to square of another big no.
