Does a shape have to be a regular polygon in order to have rotational symmetry?
A line segment would have rotational symmetry.
What polygon has rotational and line symmetry?
All regular polygons do.
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.
What figures have a rotational?
Figures that have rotational symmetry include circles, regular polygons (like squares, equilateral triangles, and hexagons), and three-dimensional shapes such as spheres, cylinders, and cones. A figure exhibits rotational symmetry if it can be rotated around a central point by a certain angle and still look the same as it did before the rotation. The angle of rotation depends on the figure; for instance, a square has rotational symmetry at 90-degree intervals, while a circle has infinite rotational symmetry.
Does a regular pentagon have rational symmetry?
A regular pentagon has rotational symmetry but does not have rational symmetry. Rational symmetry refers to the property of a shape that can be divided into equal parts by rotations that are fractions of a full rotation (e.g., 1/2, 1/3). Since a regular pentagon can only be rotated by 72 degrees (1/5 of a full rotation) to map onto itself, it does not exhibit rational symmetry.
Does a regular polygon have rotational symmetry?
Yes, because if a regular polygon is turned around a specific point (the angle of rotation) and matches up again, it has rotation symmetry. For example, a hexagon is a regular polygon with six sides. All sides are the same length and the same size. When you turn it around the angle of rotation, it matches with the next side. Therefore, all regular polygons have rotational symmetry. Hope this helps!
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
Does a shape have to be a regular polygon in order to have rotational symmetry?

What is another name for equiangular polygon?
Regular polygon Equilateral polygon Polygon with rotational symmetry
What polygon has rotational and line symmetry?
All regular polygons do.
Does a hxagon have rotational symmetry?
Yes, since it is an even-sided regular polygon.
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 lines of symmetry does a eleven sided polygon have?
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.
What is the rotational symmetry of a regular nonagon?
A regular nonagon with 9 sides has a rotational symmetry of 9.
The degree of rotation symmetry of a pentagon?
a pentagon has rotational symmetry if its a regular pentagon. if you add all 5 sides together you will get 360 degrees
Does a pentagon have rotational symmetry?
Yes, a regular pentagon has rotational symmetry.
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.
