Students learn how to use Pythagoras' Theorem to solve problems involving right-angled triangles.

As learning progresses this is linked to finding the area and perimeter of composite shapes.

**Differentiated Learning Objectives**

- All students should be able to calculate the length between two coordinate pairs.
- Most students should be able to use Pythagorasâ€™ Theorem to solve problems involving right-angled triangles.
- Some students should be able to calculate the longest diagonal in a cuboid.
