प्रश्न
Which of the figure given below have both line and rotational symmetry?
| (a) |  |
(b) |  |
| (c) |  |
(d) |  |
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°.
