An octahedron has 7 perpendicular lines.
Octagons have no 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.
An octahedron has 9 lines of symmetry. These lines can be categorized into three types: four lines that connect the midpoints of opposite edges, six lines that connect opposite vertices, and one line that runs through the centers of opposite faces. This symmetry reflects the octahedron's balanced and regular geometric structure.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of perpendicular faces will depend on which particular octahedron you have in mind. The heptagon-based pyramid, for example, has none.
Octagons have no perpendicular lines.

Each of the four lines is perpendicular - to two of the other lines.
