Chapter 12: Symmetry

Solution:-

(a)

So, the above figure has its rotational symmetry as 4.

(b)

So, the above figure has its rotational symmetry as 3.

(c) So, the given figure has only one rotational symmetry.

(d)

So, the above figure has its rotational symmetry as 2.

(e)

So, the above figure has its rotational symmetry as 3.

(f)

So, the above figure has its rotational symmetry as 4.

By observing all the figures (a), (b), (c), (d), (e) and (f) have rotational symmetry of order more than 1.
