There can be up to 8 perpendicular lines.
An octagon can have both perpendicular and parallel lines, depending on its specific configuration. In a regular octagon, opposite sides are parallel, while the angles between adjacent sides can create perpendicular lines in certain contexts. However, in an irregular octagon, the arrangement of sides and angles can vary widely, leading to different relationships between lines.
Yes 1 pair
You might be able to construct an irregular octagon that way, but for a regular one, no.
How many pairs of perpendicular sides does this figure have?
No . It is not perpendicular
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.
Perpendicular
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
Spheres do not have any perpendicular lines.
there is 15 perpendicular lines in a cube
