A cuboid
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
Diamonds come in all shapes and sizes, which determine the number of perpendicular lines (assuming you are referring to the edges as the lines) so there is no one number of lines or perpendicular lines on a diamond.
A 9 sided nonagon normally has no perpendicular lines that meet at right angles
Perpendicular lines meet at 90 degrees
A cuboid has 6 faces, 12 edges and 8 vertices which all meet at right angles.
the cuboid has 2
