How many pairs of perpendicular lines does a octogon have?

An octagon, which has eight sides, can have multiple pairs of perpendicular lines depending on how you define them. Typically, in a regular octagon, there are four pairs of perpendicular lines formed by connecting opposite vertices or by drawing lines through the midpoints of opposite sides. However, the exact count can vary if considering diagonals or other configurations. Thus, the number of pairs of perpendicular lines can differ based on the specific context or definition used.
