Students treat right-angled trigonometry as a rule to memorise rather than a relationship to understand.

Correction — Anchor the rule in a visual model first, then abstract it — the model is the explanation.

Learners apply the correct method to right-angled trigonometry but ignore the context or units.

Correction — Require an answer sentence with units on every applied question.
