They are two edges that make a 90 degree angle. However, the term is also loosely used for edges that make a 90 degree angle with the horizontal.
There is no such shape as a perpendicular prism.
Parallel edges are equidistance apart whereas perpendicular edges meet at right angle as in a square or a rectangle.
Usually not, but it can.
Each of the 12 edges of a cube is directly perpendicular to four others (two at each vertex for that edge).

none of them. The cube has parallel and perpendicular and os does the cuboid.
Usually not, but it can.
There are 12 edges in a cube.
the edges of a shape are basicly the sides of a shape
