Your description could use a bit more detail but I will list what I assume your are trying to say:
Assuming the wall and the floor are Perpendicular to each other then their intersection could represent a Right Angle. The wall and the floor also represent the intersection of two planes so their intersection also forms a line. You can see this if you look at a coordinate plane that shows x, y and z axes.
Assuming the ceiling isn’t vaulted and is flat atop four walls then it could represent a Rectangle, Square, or any other flat 4 sided figure depending on the shape of the room
Assuming the hole in the ground is round then it could represent a circle or possibly a hollow cylinder or hemisphere depends on the shape of the hole
Assuming the first kilometer of the highway is single path of travel then it could represent a horizontal line, since highways tend to be flat and run along the ground. If you include two sides then it could represent Parallel lines if you include all the sides along the highway of the first the kilometer then that could represent a Rectangle as well.
Assuming you are referring to the vertical side of the cabinet, it could represent a vertical line or vertical edge; which side of the cabinet are you referring to? If you mean the entire flat face of the cabinet then it could represent a Rectangle or Square.
I hope this helps
