A nonagon is a nine-sided polygon. In a nonagon, there are four pairs of parallel lines. This is because the nonagon can be divided into three sets of parallel lines, each containing three parallel lines. Each set of parallel lines consists of three pairs of parallel lines.
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.
Perpendicular lines meet at 90 degrees

It is possible for all nine lines to be perpendicular to at least one other line.
Well, isn't that a happy little question! A nonagon, which is a shape with nine sides, can have a total of 9 perpendicular lines. Each line would intersect the nonagon at a right angle, creating a lovely pattern of perpendicularity on its sides. Just imagine those lines dancing peacefully across the shape, creating harmony and balance.
No, it is not.
In a regular nonagon no two sides are parallel.
A nine sided nonagon has 27 diagonals
Octagons have no perpendicular lines.
An octahedron has 7 perpendicular lines.
There are four perpendicular lines in a rectangle
Each of the four lines is perpendicular - to two of the other lines.
Not sure what a dimond is but a diamond has no perpendicular lines.
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
In general, none, but there can be nine.
