Question
Choose the correct alternative:
Out of given triplets, which is not a Pythagoras triplet?
Options
(5, 12, 13)
(8, 15, 17)
(7, 8, 15)
(24, 25, 7)
Solution
(7, 8, 15)
Here, 152 = 225
72 + 82 = 49 + 64 = 113
∴ 152 ≠ 72 + 82
The square of the largest number is not equal to the sum of the squares of the other two numbers.
∴ (7, 8, 15) is not a Pythagoras triplet.
