The shape topic in GCSE Maths deals with a broad range of ideas connected with the properties of 2-d and 3-d shapes. Topics such as area, volume and symmetry are concerned mostly with the shapes themselves. Other topics, such as trigonometry and Pythagoras' theorem use the properties of triangles to calculate angles and distances in other contexts. The topics are listed here in approximately the order they should be studied, though the order becomes less important further down the list.
