All regular polygons do.
There would be too many to name. All regular polygons have a line of symmetry, but there are still polygons that don't.
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.
almost all even number of sided polygons, regular has to be
Yes they are because every polygon has at least one line of symmetry.:)
A circle (infinitely many lines of symmetry), ellipse, rectangle, and all regular polygons.
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 polygons A polygon is symmetrical if its sides that cross the line of symmetry are halved by the line of symmetry and if the sides that do not cross the line of symmetry have the same positions in space, the same lengths, and the same angles with their neighboring sides as do the sides on the other side of the line of symmetry. The only symmetrical triangles are isosceles triangles (equilateral triangles are isosceles). The only symmetrical quadrilaterals are squares, rectangles, rhombi (the line of symmetry connects either pair of opposite corners), isosceles trapezoids, and kites.
