Question 122
Which of the figures given below have both line and rotational symmetry?

Answer 1

Only (a) and (c) have both line and rotational symmetry.
In the given figure, the line of symmetry will be shown as

Also, rotational symmetry will be shown as

$\frac{{360}^{\circ }}{8}={45}^{\circ }$, i.e. rotational angle is equal to ${45}^{\circ }$

In the given figure, the line of symmetry will be shown as

Also, rotational symmetry will be shown as

$\frac{{360}^{\circ }}{10}={36}^{\circ }$, i.e. rotational angle is equal to ${36}^{\circ }$.
