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.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.

A rhombus and a hexagon are both polygons, meaning they are closed shapes with straight sides. They also both have equal interior angles - a rhombus has four equal angles, while a regular hexagon has six equal angles. Additionally, both shapes have lines of symmetry - a rhombus has two lines of symmetry, and a regular hexagon has six lines of symmetry.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.

Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
