Octagons have no perpendicular lines.
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.
An octahedron has 7 perpendicular lines.
There are four perpendicular lines in a rectangle
Each of the four lines is perpendicular - to two of the other lines.
Not sure what a dimond is but a diamond has no perpendicular lines.

9 perpendicular lines
A Star has 0 perpendicular lines!
Including its diagonals there are 6 perpendicular lines
A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.
There can be up to 8 perpendicular lines.
All regular octagons have the same number of lines of symmetry, but octagons with unequal sides would have fewer lines of symmetry.
