i. Here, 742 = 5476
242 + 702 = 576 + 4900 = 5476
∴ 742 = 242 + 702 The square of the largest number is equal to the sum of the squares of the other two numbers.
∴ (24, 70,74) is a Pythagorean triplet.
ii. Here, 272 = 729
102 + 242 = 100 + 576 = 676
∴ 272 ≠ 102 + 242
The square of the largest number is not equal to the sum of the squares of the other two numbers.
∴ (10,24,27) is not a Pythagorean triplet.
iii. Here, 612 = 3721
112 + 602 = 121 + 3600 = 3721
∴ 612 = 112 + 602
The square of the largest number is equal to the sum of the squares of the other two numbers.
∴ (11,60,61) is a Pythagorean triplet.
