Ex 12.2, 1 (b) Which of the following figures have rotational symmetry of order more than 1: Let’s rotate it by 120° This figure looks same as previous. Again, rotate it by 120° This figure looks same as previous Suppose,a it rotates by 120° again This figure looks same as previous Thus, in 1 full turn (i.e. 360°) This figure is same as that of initial 3 turns So, we say that figure has rotational symmetry of order 3
