Question

Identify, with reason, if the following is a Pythagorean triplet.

(5, 12, 13)

Answer 1

In the triplet (5, 12, 13),

5² = 25,

12² = 144,

13² = 169

5² + 12² = 25 + 144 = 169

The square of the largest number is equal to the sum of the squares of the other two numbers.

∴ (5, 12, 13) is a pythagorean triplet.
