Any regular polygon
A square has four lines of symmetry!
Number of lines of symmetry = Number of sides of the regular polygon
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
Regular polygon Equilateral polygon Polygon with rotational symmetry
10 lines. Regular polygon of "x" sides has "x" Lines of Symmetry

Any regular polygon
A regular polygon has a number of lines of symmetry equal to the number of its sides. For example, a regular pentagon has 5 lines of symmetry, while a regular hexagon has 6. Each line of symmetry divides the polygon into two congruent halves, reflecting the shape across the line.
A square has four lines of symmetry!
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.
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.
