Students learn how to calculate an angle and length in a 3D shape using trigonometry.

Later, as learning progressesÂ 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
