Question

Identify, with reason, if the following is a Pythagorean triplet.
(11, 60, 61)

Answer 1

 In the triplet (11, 60, 61),
11² = 121, 60² = 3600, 61² = 3721 and 121 + 3600 = 3721
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.
