How do you name the edge of a solid?

The edges of a solid are typically named based on the geometric shape they form. In polyhedra, for example, edges are often referred to as line segments where two faces meet. Each edge can be identified by the vertices it connects, commonly using a notation system that labels the vertices. For instance, in a cube, an edge might be named by the two corners it connects, such as "AB" for the edge between vertices A and B.
