Question

hey hiiii
step by step answer question no 9...​

Answer 1

Order of rotational symmetry = 360/30 = 12

It looks same after rotating by 30

Now Let's find at other angles

So As it has 12 order

so it would be polygon with 24 sides

So at multiples of 30 it will have rotational symmetry

60,90,120,150,180,210,240,270,300,330,360

Answer 2

I am thinking no 8

IF NO 8 WILL MOVE AT 30

it will look same at that position

I hope it will help you
