Why this why now
This unit builds on knowledge developed investigating angles and continues work done in the previous unit investigating polygons. Here pupils will develop understanding of external and internal angles of polygons and traversals through parallel lines
Prior knowledge requirements
- Identify and classify polygons by sides and angles
- Use angle rules (interior, exterior)
- Calculate sum of angles and solve problems using reasoning

Geometrical properties: polygons
In this unit pupils will investigate internal and external angles of polygons and angles made with a transveral and parallel lines. Pupils will develop their ability to formally prove properties of polygons to generalise.
