6 i think.....
none shapes have 1 rotational symmetry because in rotational symmetry one is none
The order of rotational symmetry for a shape is the number of times that it can be rotated so that it appears the same without rotation (e.g. if you rotate an equilateral triangle 60o clockwise it looks the same).For regular polygons, the order of rotational symmetry for the shape is the number of sides that it has. A hexagon has 6 sides so has order of rotational symmetry 6.
I think it has 2
All of them have rotational symmetry because all the sides and angles have to be the same in order for the polygon to be a regular polygon
Not necessarily.Not necessarily.Not necessarily.Not necessarily.
Since stars are normally spherical objects, they have rotational symmetry of infinite order.
Six.
It can do - of order 7.
it has 5 rotational symmetry
A line has rotational symmetry of order 2.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It has rotational symmetry to the order of 2
A sphere has rotational symmetry of an infinite degree.
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.
If it is a regular octagon then it has rotational symmetry to the order of 8
It has rotational symmetry of order 2.
