Description

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.

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

  1. Checking understanding of angles from KS2
  2. Securing understanding of angles from KS2
  3. Formalising understanding of triangles from KS2
  4. Formal angle notation
  5. Corresponding angles
  6. Alternate angles
  7. Co-interior angles
  8. Angles on parallel lines traversed by a straight line
  9. The sum of the interior angles of any triangle
  10. Using the sum of the interior angles of a triangle
  11. Interior angles of a polygon
  12. Deriving the sum of interior angles in multiple ways
  13. Exterior angles of polygons
  14. Interior and exterior angles of regular polygons
  15. Missing angles
  16. Problem solving with polygons
