|Figure 1: Edges of a geometric figure.||
- An edge of a 2-dimensional geometric figure is the
boundary of the figure. The figure does
not extend beyond the boundary. The word 'edge' is usually used to refer
to a straight edge. However both 'edge' and 'boundary' can be used to
refer to a curve.
- An edge of a 3-dimensional polyhedron is the line formed by the intersection of two faces.
- An edge of a network graph is a path joining two nodes.
A boundary may or may not be included in the object. When graphing,
a boundary that is not included in the object is
drawn with a dotted line. A boundary that is included in the object
is conventionally drawn with a solid line.
