It may have none, depending on its shape; the maximum is three.
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.
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.
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.

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.
The numbers that typically have two lines of symmetry are 0, 1, and 8. The number 0 has vertical and horizontal lines of symmetry, while 1 has a vertical line of symmetry. The number 8 has both vertical and horizontal lines of symmetry as well. Other numbers like 2 and 5 may have some symmetry but not consistently two lines.
No, not all lines of symmetry are diagonals. A line of symmetry is a line that divides a shape into two identical halves, which can be vertical, horizontal, or diagonal. While some shapes may have diagonal lines of symmetry, others can have vertical or horizontal lines that are not diagonal. Therefore, lines of symmetry can exist in various orientations depending on the shape.
