For a polygon with an even number of vertices
For a polygon with an odd number of vertices
You need to find a straight line which passes through the centre of the polygon, and is such that the parts of the polygon on one side of it are exactly reflected by points on the other side.

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
Because linear symmetry defines a line such that the shape is unchanged when REFLECTED in that line.
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 figure has linear symmetry when after reflection, the image looks exactly the same as the original
A scalene triangle has no axis of symmetry.
Regular polygon Equilateral polygon Polygon with rotational symmetry
A 15 sided polygon has 15 lines of symmetry;) Thanks for asking:)
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.
