The powerpoint contains a flowchart to help pupils remember which rule they should use: SOHCAHTOA, Pythagoras, sine rule or cosine rule. There are also examples of triangles to cut out and stick under the appropriate part of the flowchart. Pupils can then go ahead and actually use the rules to find the missing angles/sides/area. I wrote this to remind a Y11 class about trig before moving onto 3D problems.
