Which set does not represent the sides of a right angled triangle?1. 1

1.	Which set does not represent the sides of a right angled triangle?1. 12, 16, 202. 9, 5, 63. 6, 10, 84. 15, 25, 20
Answer» Correct Answer - Option 2 : 9, 5, 6 Explanation: For three numbers to be as per the sides of a right-angled triangle, they must satisfy Pythagoras Theorem. From Pythagoras Theorem, in a right-angled triangle, the Longest side must be the hypotenuse, and the square of the hypotenuse must be equal to the sum of squares of the other two sides. Now after checking the options, We get 9, 5, 6 is not satisfying this theorem. Since, 9² ≠ 5² + 6² 81 ≠ 61 Hence 9, 5, 6 cannot represent the sides of a right-angled triangle.

Answer» Correct Answer - Option 2 : 9, 5, 6

Explanation:

For three numbers to be as per the sides of a right-angled triangle, they must satisfy Pythagoras Theorem.

From Pythagoras Theorem, in a right-angled triangle, the Longest side must be the hypotenuse, and the square of the hypotenuse must be equal to the sum of squares of the other two sides.

Now after checking the options,

We get 9, 5, 6 is not satisfying this theorem.

Since, 9² ≠ 5² + 6²

81 ≠ 61

Hence 9, 5, 6 cannot represent the sides of a right-angled triangle.
