A triangle has 3 lines of symmetry.
a polygon
A square has four lines of symmetry!
How many lines of symmetry does the 15 side polygon have
Blue
No, a polygon can have fewer lines of symmetry.
an irregular polygon
A triangle has 3 lines of symmetry.
Number of lines of symmetry = Number of sides of the regular polygon
10 lines. Regular polygon of "x" sides has "x" Lines of Symmetry
a polygon
A 15 sided polygon has 15 lines of symmetry;) Thanks for asking:)
A square has four lines of symmetry!
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.
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.
The number of lines of symmetry in a polygon corresponds to the number of sides it has. If a polygon has n sides, then its symmetry will be n lines of symmetry and it will have one point of symmetry. A pentagon has five lines of symmetry, nonagon has 9, n-gon has n lines of symmetry, so on and so forth.
Any polygon with an even number of sides can have two lines of symmetry, but it would have to be irregular.
