How many perpendicular lines does octagon have?

An octagon has eight sides and typically does not have any perpendicular lines if it is a regular octagon, where all sides and angles are equal. However, in an irregular octagon, the number of perpendicular lines can vary depending on the specific angles formed by its sides. In general, the presence of perpendicular lines is not a defining characteristic of an octagon, but rather depends on its specific geometry.
