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.
A regular polygon that has 180 degrees is an equilateral triangle.
Regular pentagon
A regular polygon with 32 sides has 32 lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side or through the midpoints of two opposite sides. This symmetry results from the equal length and angles of all sides and vertices in the polygon.
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.
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!

The angle of rotation for a regular polygon with 7 sides isImmersive Reader
an Octagon, because 360/8=45.
360/15 = 24 degrees.
Number of lines of symmetry = Number of sides of the regular polygon
a pentagon has rotational symmetry if its a regular pentagon. if you add all 5 sides together you will get 360 degrees
If you mean a polygon with equal exterior angles of 18 degrees then it will have 360/18 = 20 sides.
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
If you rotate a 20-sided regular polygon by 360/20 degrees, the result will look the same as the original polygon. Any additional rotation will be a multiple of this number.
