उत्तर
(a) and (c)
Explanation:
Only have both line and rotational symmetry.
In the given figure, line of symmetry will be shown as
Also, rotational symmetry will be shown as
`360^circ/8` = 45°, i.e. rotational angle is equal to 45°.
In the given figure, line of symmetry will be shown as
Also, rotational symmetry will be shown as
`360^circ/10` = 36°, i.e. rotational angle is equal to 36°.
