Ex 14.2, 2 (c) Give the order of rotational symmetry for each figure: Angle at center = (360°)/3 = 120° Let’s rotate it by 120° This figure looks same as previous. Again, rotate it by 120° This figure looks same as previous Suppose, it rotates by 120° again This figure looks same as previous Thus, 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
