A heart shape It fits on itself only once back We say that a heart has…**Remember your MARGIN !!!**DATE Objectives: To be able to recognise the order of rotational symmetry of any shape**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) • Every shape has an order of rotational symmetry, even if it is order 1. (Example 2) • Have a look at the following shapes…**order 2**What is the order of rotational symmetry? answer**order 6**What is the order of rotational symmetry? answer**order 2**What is the order of rotational symmetry? answer**order 3**What is the order of rotational symmetry? answer**4**3 2 A 1 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 -3 -4
