It depends on how many sides the polygon has:
An octogon has 8 lines of symmetry, a pentagon has 5......
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
the pentagon
10 sides 10 corners (vertices), no intersecting lines a closed figure.The sides&angles are not necessarily equal, unless a regular polygon is specified. A five-pointed staractually is a 10-sided polygon (There are 5 vertices pointing 'out' and 5 pointing 'in').
a polygon can be many shapes because a polygon is A PENTAGON HEPTAGON HEXAGON NONAGON DECOGAN AND THE RDST
Whatever you like. There is nothing in the question that requires the polygon to be convex, not regular.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
An irregular polygon is a plane (2-dimensional) shape which is bounded by straight lines that meet in pairs. If all the sides are congruent AND all the angles are congruent then the polygon is regular: otherwise it is irregular.

There are many regular polygons like the square, pentagon, hexagon, and octagon
10 sides 10 corners (vertices), no intersecting lines a closed figure.The sides&angles are not necessarily equal, unless a regular polygon is specified. A five-pointed staractually is a 10-sided polygon (There are 5 vertices pointing 'out' and 5 pointing 'in').
A regular polygon like an equilateral triangle.

All the sides are equal in length.
A regular polygon with 8 sides is an octagon. Like a stop sign.
If it is a polygon then you can call it a 10000000-gon. If it's a regular polygon, then it will look almost like a circle.
