A line between 2 vertices in Graph theory is called an edge or an arc, although arc is usually used to denote a directed edge.
it is called the slope
Equilateral triangles
A line of symmetry divides a figure into two matching halves.
No. Since the graph is simple, none of the vertices connect to themselves - that is, there are no arcs that loop back on themselves. Then the two vertices with degree 6 must connect to all the other vertices. Therefore there can be no vertex with less than two arcs [ to these two vertices]. So a vertex with degree 1 cannot be part of the graph.

A line between two verticies is called a line segment.
The line is called a diagonal if it is drawn between two nonadjacent angles.
A line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
The apex Points of a triangle are called as vertices or else the points where two line segments meet is called as Vertices.
A line segment joining two adjacent vertices of a polygon is called an edge or a side. A line segment joining two non-adjacent vertices is called a diagonal.
2D shape
It is called a diagonal.
You maybe thinking of its line of symmetry or point of contact
A line segment in a polygon connecting any two nonconsecutive vertices is called a diagonal.
A diagonal of a polyhedron is a line between any two vertices except outer vertices.
If between two adjacent vertices then in 2-dimensions it is a side, in 3-d and edge. If between non-adjacent vertices, a diagonal.
No, a diagonal is never a side of a polygon:A diagonal is a line between two non-adjacent vertices of a polygon;A side is a line between two adjacent vertices of a polygon.
