Question: what are triples in math?
Answer: A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). ... A primitive Pythagorean triple is one in which a, b and c are coprime (that is, they have no common divisor larger than 1).
