Ex 14.2, 2 (a) Give the order of rotational symmetry for each figure: Let’s rotate it by 180° The figure looks same as previous Again it rotates by 180° The figure looks same as previous Thus, Thus, in 1 full-turn (i.e 360°) The figure is same as that of initial 2 turns. So, we say that this figure has rotational symmetry of order 2
