# 3D Trigonometry

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

Later, 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
