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.
a polygon
A triangle has 3 lines of symmetry.
How many lines of symmetry does the 15 side polygon have
an irregular polygon
No, a polygon can have fewer lines of symmetry.
A polygon need not have any axes of symmetry. It can have at most n axes where n is the number of sides that the polygon has.
A scalene triangle has no axis of symmetry.
Regular polygon Equilateral polygon Polygon with rotational symmetry
Number of lines of symmetry = Number of sides of the regular polygon
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.

It depends on what type of polygon.
A polygon need not have any lines of symmetry. The maximum number of lines of symmetry is attained if the polygon is regular; and this is the number of sides (or vertices) of the polygon. If a regular polygon has an even number of sides, then the lines of symmetry are those joining opposite vertices, and those joining the mid-points of opposite sides. If the polygon has an odd number of sides/vertices, the lines of symmetry are those joining each vertex to the mid-point of the opposite side.
