How many pairs of perpendicular in a square?

Answer 1

In a square, there are four pairs of sides that are perpendicular to each other. Each side of the square forms a right angle (90 degrees) with its adjacent sides. Therefore, the four pairs of perpendicular sides are: (top, left), (top, right), (bottom, left), and (bottom, right). Additionally, the diagonals of the square are also perpendicular to each other, adding one more pair, resulting in a total of five pairs of perpendicular lines.
