Hello! I have a homework for tomorrow. The question is: What are the consequences of the Pythagorean theorem?? On Wikipedia, they mixed the consequences and the uses of the theorem in one paragraph: 5.1 Pythagorean triples 5.2 Incommensurable lengths 5.3 Complex numbers 5.4 Euclidean distance in various coordinate systems 5.5 Pythagorean trigonometric identity 5.6 Relation to the cross product I assume that the first two are the consequences, and the rest are the uses of the theorem, but I want to be 100% sure. Any help?

Personally, I would say that 5.3 and 5.4 are uses because they are definitions, while the rest are consequences because they are derived from the theorem.
