mabe because irregular heptagon looks different all the time
In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.

Ah, isn't that a lovely question? An irregular octagon can have anywhere from 0 to 8 lines of symmetry, depending on its shape. Each side and angle must be carefully considered to determine the number of lines of symmetry in this unique and special shape. Just take your time, look closely, and you'll find the beauty in its symmetry, no matter how many lines there may be.
No.It is regular because it has at least one line of symmetry
it has 8 ( there's lines in the middle of the sides) * * * * * No it does not - not if it is an irregular octagon.

No, it has seven.
Irregular quadrilateral
All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).
A heptagon has seven sides, so it will have seven lines of symmetry. Each line of symmetry will pass through a vertex and the midpoint of the opposite side. These lines divide the heptagon into mirror-image halves, making it symmetrical.
Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
An irregular pentagon.
square, septagon (heptagon)!
