Which of the following is a Pythagorean triple?

A. (5, 12, 13)

B. (1, 1, 2)

C. (3, 4, 6)

D. (5, 8, 10)

A

Step-by-step explanation:

Perhaps you know of the {3, 4,5} Pythagorean triple.

Pythagoras stated a² + b² = c²

so checking for A:

a² + b² = c²

5² + 12²

25 + 144 = 169 which is 13²

Only answer A. (5, 12, 13) is a Pythagorean triple.

The others are not.
