It is possible for all nine lines to be perpendicular to at least one other line.

Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
A cuboid has 6 faces, 12 edges and 8 vertices which all meet at right angles.
how many sets of parallel lines are in a triangle
If by two sets of perpendicular lines you mean two pairs of perpendicular lines we can do it. One set of parallel lines is easy so draw that as the first and second lines A right angle from one of them will intersect the other at a right angle so that's the third line and the right angles sorted. The fourth side cannot be parallel to the third so draw it at an angle to the third. We now have two right angles, one set of parallel lines and two pairs of perpendicular lines, first and third, and second and third. What we call it depends on where we are. In the UK it is called a trapezium and in the USA a trapezoid. I'm afraid I don't know naming conventions in other countries.

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.
4, one set at each corner.
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
rhombus
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
A diamond shape, or rhombus, has two pairs of perpendicular lines. The diagonals of the diamond intersect at right angles, creating four right angles at the intersection point. Thus, while there are two sets of diagonals, the key perpendicular lines are the diagonals themselves.
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 shape that has two sets of perpendicular lines is a rectangle. In a rectangle, opposite sides are equal in length, and the angles formed at the corners are right angles, which are 90 degrees. Additionally, a square is a specific type of rectangle that also has all sides of equal length. Both shapes feature two sets of perpendicular lines.
Rectangles are made up of 2 sets of parallel lines, which are perpendicular to one another.
The description given could be that of a rectangle.
A shape that has 2 parallel lines and 4 perpendicular lines is a rectangle. In a rectangle, the opposite sides are parallel, while the adjacent sides are perpendicular to each other. Therefore, a rectangle fits the description of having two sets of parallel lines and four right angles formed by the perpendicular lines.
