Trigonometry in 3D (without sine or cosine rules)

This resource is for KS4 pupils taking the Higher paper. The objective of the resource is to help pupils tackle 3D problems where they need to apply Pythagoras’ Theorem and trigonometry in right-angled triangles.

The presentation has a starter, an example and worked solutions to the 4 questions on the worksheet. The shapes covered are cuboids, pyramids, cylinders and wedges.

(There is another resource available which requires the application of the sine and cosine rules in similar problems).
