Lines of symmetry must be equal halves.
rectangles
A regular hexagon has more than 4 lines of symmetry. Even number sided polygons that are regular and have more than 4 sides have more than 4 lines of symmetry. Circles have more than four lines of symmetry. Squares also have 4 lines of symmetry.
A hexagon has 6 lines of symetry and a dodecagon has 12. The number of sides equal the number of ines of symetry
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry

If you're talking about convex polygons with equal sides (eg. equilateral triangles, squares, pentagons, hexagons, etc.), then the relationship is a very direct one. In those cases, there are as many lines of symmetry as there are points in the polygons. A triangle has three lines of symmetry, a square has four, a pentagon five, etc.
