Question

Which set of side lengths is a Pythagorean triple? 2, 3, 13 5, 7, 12 10, 24, 29 11, 60, 61

Answer 1

11, 60, 61 side lengths are a pythagorean triple.

Answer 2

Answer: The correct answer is "11,60 and 61".

Explanation:

The expression from the Pythagoras theorem in the right triangle is as follows;

`AC^(2) =BC^(2) + AB^(2)` ...... (1)

Here, AC is the longest side which is hypotenuse, AB is the shortest side which is perpendicular in the right triangle and BC is the side of the triangle.

Only 11, 60 and 61 satisfies the above expression.

`(61)^(2) =(60)^(2) + (11)^(2)`

`3721=3600+121`

`3721=3721`

Therefore, L.H.S is equal to R.H.S. It satisfies the Pythagoras theorem.
