Ex 14.3, 7 Can we have a rotational symmetry of order more than 1 whose angle of rotation is (i) 45Β°? Order of rotational symmetry = (360Β°)/(π΄ππππ ππ π π¦ππππ‘ππ¦) = (360Β°)/(45Β°) = (72Β°)/9 Since, order of rotational symmetry is an integer Hence it is possible Ex 14.3, 7 Can we have a rotational symmetry of order more than 1 whose angle of rotation is (ii) 17Β°?Order of rotational symmetry = (360Β°)/(π΄ππππ ππ πππ‘ππ‘ππππ ) = (360Β°)/(17Β°) = 21 (3Β°)/17 Since, order of rotational symmetry is in fraction This is not possible
