To solve problems involving trigonometry in 3D shapes students are taught to identify 2D right-angled triangles and apply the Sine, Cosine and Tangent ratios.  As learning progresses they consider square based pyramids in addition to cubes and cuboids.

Differentiated Learning Objectives

• All students should be able to calculate a length in a 3D shape using 2D representations of right angled triangles
• Most students should be able to calculate an angle in a 3D shape using 2D representations of right angled triangles.
• Some students should be able to calculate a combination of length and angle in a 3D shape using 2D representations of right angled triangles
