Mention the order of rotational symmetry in the following figures: [4 MARKS]

Mention The Order Of Rotational Symmetry In The Following Fi...

Answer:
:
Figures with order of symmetry 4: 1 Mark
Figures with order of symmetry 3: 1 Mark
Figures with order of symmetry 2: 1 Mark
Figures with order of symmetry 1: 1 Mark
Figures (a) and (f) will look the same if rotated by 90

^{o}

, 180

^{o}

, 270

^{o}

or 360

^{o}

. Hence, they have an order of 4.
Figures (b) and (e) will look the same if rotated by 120

^{o}

, 240

^{o}

or 360

^{o}

. Their order of rotational symmetry will thus be 3.
If we rotate figure (d) by 180

^{o}

or 360

^{o}

, we will get the same figure. Hence, it has an order of 2.
But option (c) has an order of only 1 since the same figure can be obtained if the figure is rotated by 360

^{o}

.
