Before reading this guide, it may be helpful to read the guides from Module 1 on the properties of angles and the properties of 2D shapes. The sum of the angles inside any polygon can be found by ...

Circle theorems are used in geometric proofs and to calculate angles. Transformations - Edexcel Transformations change the size or position of shapes. Congruent shapes are identical, but may be ...

Create new shapes that always have the same side lengths. Experiment with the circle as a tool to make new sides. Dynamic geometry software (DGS) is a powerful tool for improving student learning.
