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.
There could be many answers to this. If were thinking in terms of geometry: a triangle has between 1 and 3 lines of symmetry a square will always have 4 lines of symmetry. Irregular shapes might have a single line of symmetry. For instance, a building may have a single line of symmetry. a line between two points may only have one line of symmetry. because it is only 2 dimensions, it is impossible for it to have more than one line of symmetry.
Line symmetry is when a mirror line can be drawn so that each half is a reflection of the other half. The only one of {2, 4, 6, 8} with any possible line symmetry is the 8. Depending upon how it is written, it may have one or two 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 square has 4. A pentagon may have 0, 1 or 5.
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.

Only if its in the form of an equilateral triangle or a isosceles triangle will it have 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.
This varies according to the polygon. A polygon is any 2D closed shape with three or more straight sides. Therefore, a polygon such as a square will have four lines of symmetry, but an irregular hexagon may have several or none. Even a triangle can have between zero and three lines of symmetry, depending on the type of triangle it is.

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.
