A regular octogan has 8 lines of symetry, and a irregular octogan has 2 lines of symetry.
I have no idea about an octogan. An octagon can have none, one, two, up to 8 lines of symmetry.
2d shapes do not have edges or vertices
It can have 0, it can have 8, and some numbers in between.
no an octogan has eight sides while a hexagon only has six sides
A regular octagon has 8 interior obtuse angles.
