In a trapezium, there are two perpendicular lines. These perpendicular lines are the diagonals of the trapezium. The diagonals of a trapezium are the line segments that connect non-adjacent vertices of the trapezium and intersect each other at a right angle.
A cuboid has 12 edges, and each edge is perpendicular to 4 other edges. Thus, in total, there are 12 pairs of edges that are perpendicular to each other. However, if considering distinct perpendicular lines, a cuboid effectively has 3 sets of three mutually perpendicular lines, corresponding to its three dimensions (length, width, and height).
A cuboid has 6 faces, 12 edges and 8 vertices which all meet at right angles.
the cuboid has 2

In a cuboid, there are three pairs of opposite faces, and each pair can be considered perpendicular to the other pairs. Therefore, a cuboid has a total of six edges, and each edge is perpendicular to four other edges. Overall, in a cuboid, there are 12 perpendicular relationships between edges.
two.
A cuboid has a total of six faces. Each face of the cuboid is perpendicular to four other faces. Specifically, each face is parallel to one opposite face and perpendicular to the other four faces.
Octagons have no perpendicular lines.
