A set of numbers forms a Pythagorean triple if the square of the largest number is equal to the sum of the squares of the other two numbers. In mathematical terms, for a set of numbers \(a\), \(b\), and \(c\) (where \(c\) is the largest), the condition is:

\[ c^2 = a^2 + b^2 \]

Let's check each of the provided sets:

  1. 9, 12, 14

    • The largest number is 14.
    • \(14^2 = 196\)
    • \(9^2 + 12^2 = 81 + 144 = 225\)
    • \(196 \neq 225\)
  2. 5, 12, 13

    • The largest number is 13.
    • \(13^2 = 169\)
    • \(5^2 + 12^2 = 25 + 144 = 169\)
    • \(169 = 169\) (This is a Pythagorean triple)
  3. 10, 24, 26

    • The largest number is 26.
    • \(26^2 = 676\)
    • \(10^2 + 24^2 = 100 + 576 = 676\)
    • \(676 = 676\) (This is also a Pythagorean triple)
  4. 6, 8, 11

    • The largest number is 11.
    • \(11^2 = 121\)
    • \(6^2 + 8^2 = 36 + 64 = 100\)
    • \(121 \neq 100\)

The sets that form Pythagorean triples are 5, 12, 13 and 10, 24, 26.
