The order of rotational symmetry in the Fig given below is: 7
1 4
2 8
3 6
4 Infinitely many
Explanation:
6 Since, the number of times a figure fits onto itself in one full turn is called order of rotational symmetry. Therefore, the given figure has rotational symmetry of order 6.

Mark \((\checkmark)\) against the correct answer. In the given figure, AOB is a straight line, \(\angle\text{AOC}=68^\circ\) and \(\angle\text{BOC}=\text{x}^\circ\). The value of x is: 8
1 32
2 22
3 112
4 132
Explanation:
112 In the figure \(\angle\text{AOC}=68^\circ\) But \(\angle\text{AOC}+\angle\text{BOC}=180^\circ\) (Linear pair) \(68^\circ+\text{x}=180^\circ\) \(\Rightarrow\text{x}=180^\circ-68^\circ=112^\circ\)
