# NCERT Solutions  for Class 7th Maths Exercise – 14.2 Chapter – 14 Symmetry

Q1. Which of the following figures have rational symmetry of order more than 1:

Solution:-

(a)

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

(b)

So, the above figure has its rotational symmtry 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.

Q2. Give the order of rotational symmetry for each figure:

(a)

Solution:-

The above figure has its rotational symmetry as 2.

Solution:-

The above figures has its rotational symmetry as 2.

( c )

Solution:-

The above figure has its rotational symmetry as 3.

(d)

Solution:-

The above figure has its rotational symmetry as 4.

( e )

Solution:-

The above figure has its rotational symmetry as 4.

(f)

Solution:-

The above figures has its rotational symmetry as 5.

(g)

Solution:-

The above figures has its rotational symmetry as 6.

(h)

Solution:-

The above figure has its rotational symmetry as 3.
