They may have no lines of symmetry or they may have some - it all depends upon the shape of the irregular octagon. Only regular octagons have 8 lines of symmetry.
A dodecagon has 12 sides, so it has 12 lines of symmetry. Each line of symmetry divides the dodecagon into two equal halves, making it look like a mirror image. So, if you're ever in doubt, just remember that a dodecagon is as symmetrical as a Kardashian selfie.
It depends on what shape the glass is.
A square has 4. A pentagon may have 0, 1 or 5.
One or none.
They may have no lines of symmetry or they may have some - it all depends upon the shape of the irregular octagon. Only regular octagons have 8 lines of symmetry.
If it is a regular 8 sided octagon then it will have 8 lines of symmetry
Different triangles may have none, one, or three lines of symmetry.
Only if its in the form of an equilateral triangle or a isosceles triangle will it have lines of symmetry.
A regular octagon has 8 lines of symmetry. See the Related Link below that includes a diagram of an octagon with the lines of symmetry drawn. A non-symmetrical octagon may have between 0-4 lines of symmetry.
A rhombus has two lines of symmetry. They are also called its diagonals. Suppose there is a rhombus ABCD AC and BD are its lines of symmetry.

A regular pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon.An irregular pentagon may have none or 1 line of symmetry.

It may have none, depending on its shape; the maximum is three.
Yes, a trapezoid may have two lines of symmetry, but the trapezoid must also be a rectangle.If the trapezoid is not also a rectangle, the the most symmetry lines it can have possible is 1 (this can only occur it's an isosceles trapezoid.)
