There are no perpendicular lines in a regular octagon. Perpendicular lines are found in squares and rectangles, where the angles are 90 degree angles. Regular octagons, unlike squares, have so many sides that the angles joining the sides cannot be as sharp as 90 degrees. Instead, the angles are much larger and the sides are much too wide apart to be anywhere near perpendicular.
It is possible, however, to construct an irregular octagon having perpendicular lines.
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.
Four * * * * * If the question refers to an octagon, rather than an octogan, it can have 8 lines of symmetry although it need not have any.

It can have 0, it can have 8, and some numbers in between.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Perpendicular lines intersect.

Lines that aren't perpendicular
perpendicular.
Lines that intersect at 90 degrees are perpendicular lines
A rhombus has parallel lines but no perpendicular lines.
