Full lesson which investigates interior and exterior angles in polygons with the aim of the students generalising what they have found to any n-gon.
The lesson begins with a quick recap on angles before taking students though the necessary steps of the investigation. The plenary tasks give students the chance to practise using the formulae they have found for shapes of n sides.
The resource comes with a table for students to fill in as they go, as well as a sheet of instructions which you could give to extend some learners.
