If the question refers to an octagon, rather than an octogan, it can have 8 lines of symmetry although it need not have any.
I have no idea about an octogan. An octagon can have none, one, two, up to 8 lines of symmetry.
A regular octogan has 8 lines of symetry, and a irregular octogan has 2 lines of symetry.
A regularpentagon has 5 lines of symmetryAny pentagon could have less and so can have up to 5 lines of symmetry.
A right angle has one line of symmetry.
The letter "S" has no lines of symmetry. It does not exhibit reflectional symmetry along any axis, as its shape does not mirror itself when divided.
I have no idea about an octogan. An octagon can have none, one, two, up to 8 lines of symmetry.
It can have 0, it can have 8, and some numbers in between.
A regular octogan has 8 lines of symetry, and a irregular octogan has 2 lines of symetry.
a square has 4 lines of symmetry.
There are 6 lines of symmetry if you count sides and not just vertices. (=
A regular hexagon has six lines of symmetry. Lines of symmetry are imaginary lines where you can fold a figure or image and both halves are identical matches.
a rectangle has 4 lines of symmetry
A regularpentagon has 5 lines of symmetryAny pentagon could have less and so can have up to 5 lines of symmetry.

A trapezium has normally no lines of symmetry unless it is an isosceles trapezium which has 1 line of symmetry
A right angle has one line of symmetry.
