Remember your MARGIN !!! DATE Objectives: To be able to recognise the order of rotational symmetry of any shape
4
Rotational Symmetry The order of rotational symmetry of a shape is determined by how many times the shape fits onto itself during a 360° turn. (Example 1)(Example 1) Every shape has an order of rotational symmetry, even if it is order 1. (Example 2)(Example 2) Have a look at the following shapes…
