It has rotational symmetry to the order of 2
A regular nonagon with 9 sides has a rotational symmetry of 9.
Rotational symmetry of order 1.
A line has 180 degrees rotational symmetry.
They have not got any rotational symmetry
it has 5 rotational symmetry
A sphere has rotational symmetry of an infinite degree.
A star
Since stars are normally spherical objects, they have rotational symmetry of infinite order.
6 i think.....
Six.
It can do - of order 7.

Rotational symmetry is determining whether a shape has symmetry when it is rotated from the center. For example: if you have a star fish, it does have rotational symmetry because you can rotate the star fish 5 times and their still be symmetry. If the object has rotational symmetry, you then can determine the percentage and order of the ratational symmetry. The percentage is how much out of 100% the object is rotated to find symmetry. The order is how many times it is to be rotated before the object has returned to its origiinal position. Take the star fish example. It can be rotated 5 times (each turn having symmatry). The percentage of rotation would be 20%, and the order would be 5.
A regular pentagon or a 5-pointed star have rotational symmetry of order 5.
