yes
almost all even number of sided polygons, regular has to be
All regular polygons do.
No, it's not true that only regular polygons with an even number of sides are symmetrical. Regular polygons, regardless of whether they have an even or odd number of sides, are symmetrical. They possess rotational symmetry and reflectional symmetry; for example, a regular triangle (3 sides) and a regular pentagon (5 sides) both exhibit symmetry.
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
Regular polygons.
no
Yes It Does
yes

All regular polygons do.
All regular ones do.
All of them have rotational symmetry because all the sides and angles have to be the same in order for the polygon to be a regular polygon
yall get on my nerves

There would be too many to name. All regular polygons have a line of symmetry, but there are still polygons that don't.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
