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.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.

Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
i dont know man
rectangles
squares and rectangles
Square, rectangle, rhombus
rhombus, rectangle etc.
Lines of symmetry must be equal halves.
Regular polygons.
rhombus,parralellagram ,rectangle
All regular ones do.
Providing that it is a regular 9 sided nonagon it will have 9 lines of symmetry
