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 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.

Lines of symmetry in polygons are not necessarily diagonals. A line of symmetry divides a shape into two identical halves, while a diagonal connects non-adjacent vertices of a polygon. In some cases, a diagonal can serve as a line of symmetry, but this is not true for all polygons. Therefore, while there can be overlap, the two concepts are distinct and not synonymous.
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.
