Teaching guide
What students learn
Solve practical problems with Pythagoras' theorem and right-angled trigonometry, including direction and angles of elevation and depression.
Worked example
A right triangle has hypotenuse 15 and one leg 9. Find the other leg.
Answer: 12
Why: sqrt(15^2 - 9^2) = sqrt(225 - 81) = sqrt(144) = 12
Generated and checked in code, so it is correct.
