Rectangle, and equilateral/icoscles triangle, and a pentagon
Lines of symmetry must be equal halves.
rectangles
Polygons that have only two lines of symmetry include the rectangle, the isosceles triangle, and the kite. A rectangle has vertical and horizontal lines of symmetry, while an isosceles triangle has a single line of symmetry through its vertex. A kite has two lines of symmetry that intersect at its center. Each of these shapes exhibits symmetry in a limited manner compared to more symmetric polygons like squares or equilateral triangles.
Providing that it is a regular 9 sided nonagon it will have 9 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

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.
A polygon that has four lines of symmetry is a square. The lines of symmetry in a square include two diagonal lines and two lines that bisect the sides vertically and horizontally. Other polygons, such as the rectangle (not a square) and certain types of rhombuses, can also have four lines of symmetry, depending on their specific dimensions and angles. However, the square is the most common example of a polygon with exactly four lines of symmetry.
