Which one is a right triangle and not a right triangle

15, 8, 17

Step-by-step explanation:

In order to be a right triangle, the side lengths must satisfy Pythagorean Theorem: a² + b² = c² ; where a and b are the legs (smallest side lengths) and c is the hypotenuse (largest side length).

Let's try 10, 11, 15:

10² + 11² = 15²

100 + 121 = 225

      221   = 225

 FALSE → not a right triangle

Let's try 15, 8, 17:

15² + 8² = 17²

225 + 64 = 289

      289   = 289

 TRUE → is a right triangle!
