Look at the following shapes Label them using the following code: R = it has rotational symmetry N = no rotational symmetry 0 = no plane of symmetry 1 = 1 plane of symmetry 2 = 2 planes of symmetry 3 = 3 planes of symmetry 4 = 4 planes of symmetry etc E.g. N2: no rotational symmetry, 2 planes of symmetry © T Madas
