Are 9 12 15 pythagorean triples?

No, the numbers 9, 12, and 15 do not form a Pythagorean triple. A Pythagorean triple consists of three positive integers (a), (b), and (c) such that (a^2 + b^2 = c^2). In this case, if we take 15 as the largest number, (9^2 + 12^2 = 81 + 144 = 225), which equals (15^2). Therefore, 9, 12, and 15 do indeed form a Pythagorean triple.
