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.
All regular ones do.
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.
