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

(3, 5, 4)

###### Advertisements

#### Solution

In the triplet (3, 5, 4),

3^{2} = 9, 5^{2} = 25, 4^{2} = 16 and 9 + 16 = 25

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

∴ (3, 5, 4) is a pythagorean triplet.
