Ex 12.2, 2 (f) Give the order of rotational symmetry for each figure: In case of regular pentagon, We rotate it about the center Let’s rotate it by 72° The figure looks the same as previous Now suppose it rotates by 72° again The figure looks the same as previous Again it rotates 72° The figure looks the same as previous Once again, it rotates 72° The figure looks the same as previous Suppose, it again rotates by 72° The figure looks the same as previous Thus, The figure is same as that of initial 5 turns. So, we say that figure has rotational symmetry of order 5.
