Straight and Curved.
A line?
All 12 sides are straight! This is a 2 dimensional object. * * * * * A dodecahedron is NOT a 2 dimensional object so the above answer is utter nonsense. A dodecahedron has pentagonal faces.
As long as they are not parallel, they will meet at an "edge", which is just a straight line.
If the faces are flat, it's a line.
An octagon has 8 faces and 8 edges. Each face of an octagon is a straight line segment, and each edge is a line segment where two faces meet. The total number of faces and edges in an octagon can be calculated by adding the number of faces and edges together, which equals 16.
[A Parallel line is a straight line, opposite to another, that do not intersect or meet.] Ie. Line 1 is Parallel to Line 2. ------------------------------------------------- <Line 1 ------------------------------------------------- <Line 2

When 2 or more straight lines meet...the point where they meet is called the point of intersection
the edge
no they are a line that join to faces e.g take 2 faces from a square and in the middle is a vertices

No because a defined straight line has 2 end points.
