Does a shape have to be a regular polygon in order to have rotational symmetry?
A line segment would have rotational symmetry.
What is a symmetrical polygon?
As the name suggests, they are polygons that have one or more lines of symmetry or rotational symmetry of order two or more. A symmetric polygon is not the same as a regular polygon.
How many order of rotational symmetry does a octagon have?
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
What are the rotational symmetry of a 5 sided shape?
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
What shapes have 1 order of rotational symmetry?
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
What regular polygons have rotational symmetry?
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

What is the rotational symmetry of a regular nonagon?
A regular nonagon with 9 sides has a rotational symmetry of 9.
What is the order of rotational symmetry an octagon?
If it is a regular octagon then it has rotational symmetry to the order of 8
How do you sketch a figure with rotational symmetry but no line symmetry?
When a shape is rotated about its centre, if it comes to rest in a position and looks exactly like the original, then it has rotational symmetry. A shape like an equilateral triangle would therefore have an order of rotational symmetry of 3. The general rule for a regular polygon (shapes such as pentagons, heptagons, octagons etc. is, that the number of sides is the same as the number of lines of symmetry, which is also the same as the rotational symmetry order). This means that a regular hexagon has 6 sides, 6 lines of symmetry and an order of rotational symmetry of 6. Following from this, then a square, which is a regular polygon, has 4 sides, 4 lines of symmetry and an order of rotational symmetry of 4. If a shape has rotational symmetry, it must have either line symmetry or point symmetry or both. For example, a five pointed star has 5 lines of symmetry and rotational symmetry of order 5, but does not have point symmetry. A parallelogram has no line of symmetry, but has rotational symmetry of order 2 and also point symmetry. Only a shape which has line symmetry or point symmetry can have rotational symmetry. When there is point symmetry and also rotational symmetry, the order of the latter is even. For example, the letter 'S' has rotational symmetry of order 2, the regular hexagon of order 6. On this basis, we would suggest that the letter 'F' does not have a rotational symmetry order as it does not have either line symmetry or point symmetry. It doesn't have a centre around which you could rotate it. Sounds weird, but given the definitions, we think this is the case.
A polygon with Rotational symmetry order of 3 is?
A shape like an equilateral triangle would therefore have an order of rotational symmetry of 3
What is the order of symmetry of an octagon?
If it is a regular octagon then it has rotational symmetry to the order of 8
How many order of rotational symmetry does a octagon have?
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
Is a nonagon symmetrical?
Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
Is a regular pentagon rotational or reflectional symmetry?
It has both because it has 5 lines of symmetry and rotational symmetry to the order of 5
Does a decagon have rotational symmetry?
heck yeah it does * * * * * It can do, but it need not have any non-trivial rotational symmetry. A regular decagon will have rotational symmetry of order 10.
