Pythagoras and Trigonometry
Identify the hypotenuse and label opposite/adjacent relative to the stated angle before choosing a ratio.
Key ideas
- Pythagoras
- sine/cosine/tangent
- inverse trig
- angles of elevation
- multi-step problems
Formula / rule: a²+b²=c²; SOH–CAH–TOA.
Worked example: θ=sin⁻¹(opposite/hypotenuse) when the angle is unknown.
Common trap: Calculator angle mode must match the units expected, usually degrees in school problems.
Key words
sine — opp/hyp
cosine — adj/hyp
tangent — opp/adj
inverse trig — operation used to find an angle from a ratio
hypotenuse — side opposite 90°
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
