Answer:
d) (18,20,25) is not a Pythagorean triplet
Step-by-step explanation:
Three numbers are said to be Pythagorean triplets if the sum of squares of two smaller numbers is equal to the square of largest number.
The 1st 2nd and 3rd groups satisfy the condition of Pythagorean triplet but the fourth one doesn't
18^2+20^2=724 but 25^2=625
Therefore the 4th group is not a Pythagorean triplet.
