Edge
Revision as of 12:38, 30 January 2014 by Zhuangzhuang (talk | contribs)
An edge of a polygon or polyhedron is a line segment whose endpoints are two adjacent vertices of the figure. In the case of polygons, an edge joins two consecutive vertices. In the case of polyhedra, an edge joins two vertices and is the boundary between two adjacent faces. An edge can also be part of a graph.
