What students learn
Use Pythagoras' theorem to find unknown side lengths of right-angled triangles.
Worked example
A right triangle has hypotenuse 13 and one leg 5. Find the other leg.
Answer: 12
Why: sqrt(13^2 - 5^2) = sqrt(169 - 25) = sqrt(144) = 12
Generated and checked in code, so it is correct.
