## Determining if Vectors are Parallel

## Sine Rule: Finding Missing Sides

## 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.

## Compound Measures – Calculating Speed

A really quick introductory exercise on calculating speed – intentionally created to develop the concept of speed – rather than something they immediately need a triangle for!
