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.

Each of the four lines is perpendicular - to two of the other lines.
