Definition
Let $\tuple {x, y, z}$ be a primitive Pythagorean triple.
The convention for representing $\tuple {x, y, z}$ as a (primitive) Pythagorean triple is that $x$ is the even element, while $y$ and $z$ are both odd.
This is the canonical form of a Pythagorean triple.

Hence $z$ must also be odd.
