Some clever variable-substitution trickery to randomly pick two sides of a right-angled triangle to give to a student, and ask for the other.
The sides are set up so they're always Pythagorean triples, and the opposite side is always odd.

Because this was created quickly to show how to set up the randomisation, there's no diagram. It would benefit greatly from a diagram.
