Yes
It has both.
Opposite edges are parallel to each other in a cube
Each of the 12 edges of a cube is directly perpendicular to four others (two at each vertex for that edge).

A cube has 12 edges, and each edge is perpendicular to 4 other edges. However, since each perpendicular relationship is counted twice (once for each edge), the total number of unique perpendicular line segments in a cube is 12. Thus, a cube has 12 perpendicular line segments.

Yes

There are 12 edges in a cube.
Yes. Adjacent sides in a cube are perpendicular and planes that are perpendicular to the same plane are parallel.
Oh, dude, you're hitting me with the geometry questions, huh? So, like, a shape that fits that description would be a triangular prism, because it has perpendicular edges but none that are parallel. It's like the rebel of the 3D shapes, just doing its own thing.

In any cube, you can sort the edges into three sets, with 4 edges in each set. All four edges in a set are parallel to each other, and none of the edges in one set is parallel to any of the edges in any other set.
