3D Trigonometry - Cuboids WORKSHEET

Suitable for Year groups: Year 10, Year 11
GCSE Tier: Higher
Targeting grades: 6-7
Prerequisite knowledge: Apply trigonometric ratios to find angles and lengths in right angled triangles.
Learning Objective: Apply trigonometric ratios to find angles and lengths in three dimensional figures.

3D Trigonometry - Cuboids WORKSHEET DESCRIPTION

This worksheet provides a series of exercises focused on applying trigonometry in cuboids and provides an excellent, guided introduction to applying trigonometry in 3D shapes in general, especially for students who struggle with spatial reasoning.

To begin with, learners will find different angles and diagonal lengths on the surface of cubes, considering which right angled triangles can be seen and used on the shapes. Students will progress to calculating more abstract lengths and angles within cubes and we have highlighted useful triangles as scaffolding.

The same steps are followed to boost students' confidence as they begin to calculate lengths and angles in cuboids.

All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions

Students should be confident applying trigonometric ratios to find angles and lengths in right angled triangles before tackling 3D work. This foundation is essential because the worksheet builds upon these 2D skills by helping learners identify which right angled triangles exist within cuboids and cubes. Without solid grasp of basic trigonometry, students will struggle to make the leap into three-dimensional applications.
