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 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.
