For a polygon with an even number of vertices
- join each vertex to the opposite vertex. Test for symmetry.
- join the mid-point of each side to the mid-point of the opposite side. Test for symmetry.

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 is a figure with no symmetry lines?

How many lines of symmetry does a regular polygon with 20 sides have?
How many lines of symmetry does the 15 side polygon have
What do you call a polygon with no lines of symmetry?

Will the number of lines of symmetry for a polygon always be the same as the number of vertices?
No, a polygon can have fewer lines of symmetry.
How many axes of symmetry does a polygon have?
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.
Why linear symmetry is called reflection symmetry?
Because linear symmetry defines a line such that the shape is unchanged when REFLECTED in that line.
What polygon that does not have line of symmetry?
A scalene triangle has no axis of symmetry.
What is another name for equiangular polygon?
Regular polygon Equilateral polygon Polygon with rotational symmetry
What is linear symmetry?
A figure has linear symmetry when after reflection, the image looks exactly the same as the original
What is the rule for the number lines of symmetry of any regular polygon?
Number of lines of symmetry = Number of sides of the 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.
