उत्तर

(3, 4, 5)

Explanation:

(A) In the triplet (1, 5, 10),

12 = 1, 52 = 25, 102 = 100 and 1 + 25 = 26 ≠ 100 

The square of the largest number is not equal to the sum of the squares of the other two numbers.

∴ (1, 5, 10) is not a Pythagorean triplet.

(B) In the triplet (3, 4, 5),

32 = 9, 42 = 16, 52 = 25 and 9 + 16 = 25

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

∴ (3, 4, 5) is a Pythagorean triplet.

(C) In the triplet (2, 2, 2),

22 = 4, 22 = 4, 22 = 4 and 4 + 4 = 8 ≠ 4

The square of the largest number is not equal to the sum of the squares of the other two numbers.

∴ (2, 2, 2) is not a Pythagorean triplet.

(D) In the triplet (5, 5, 2),

22 = 4, 52 = 25, 52 = 25 and 4 + 25 = 29 ≠ 25

The square of the largest number is not equal to the sum of the squares of the other two numbers.

∴ (5, 5, 2) is not a Pythagorean triplet.
