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 pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon.An irregular pentagon may have none or 1 line of symmetry.
A regular polygon with x sides has x lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. For example, a regular hexagon has 6 lines of symmetry, one for each pair of opposite sides. The formula for calculating the number of lines of symmetry in a regular polygon is equal to the number of sides x.
10 lines. Regular polygon of "x" sides has "x" Lines of Symmetry
A 15 sided polygon has 15 lines of symmetry;) Thanks for asking:)
It depends on what type of polygon.
It has 32 lines of symmetry.
A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.
A regular 20-gon has 20 lines of symmetry. Each line of symmetry can be drawn through a vertex and the midpoint of the opposite side, or through the midpoints of two opposite sides. This symmetry reflects the polygon's regularity, as all sides and angles are equal.
1 - through the vertex
1 - through the vertex
It has 3 lines of symmetry which are the perpendiculars taken from each vertex to the opposite base
