Trigonometry – Missing Angles

Created this in order to try and overcome the problem of students seeing trigonometry of ‘that thing with SOH CAH TOA’ and it being something entirely procedural. My Year 9s are getting on really well with this – question 10 is a wonderful discussion point.

NB. Have intentionally not varied orientation of triangles here – that’s something that I will do in a separate exercise.
