On edge definition math. In an object the line which passes through the two faces or the line joining two vertices is called the edge. In a polygon an edge is a line segment on the boundary and is often called a side. A segment joining two vertices while passing through the interior or exterior is not an edge but instead is called a diagonal. Let s look at thomas s ice cream cone but let s make the cone have a flat closed top where the ice cream sits.

Vertex plural vertices a line or border at which a shape or surface terminates. Where two squares meet a line segment is formed which is called an edge. A face is a single flat surface. This tetrahedron has 6 edges.

Set one s teeth on edge. Late 1800s also see on the edge. Vertices is a point where two or more line segments meet. This tetrahedron has 4 vertices.

A line segment on the boundary joining one vertex corner point to another. A line segment where two faces meet. Edge the side of a polygon or a line segment where two faces of a solid figure meet. Let us look more closely at each of those.

In a polyhedron or more generally a polytope an edge is a line segment where two faces meet. This pentagon has 5 edges. An edge is a line segment between faces. In any geometric solid that is composed of flat surfaces faces an edge is a line segment where two such surfaces meet.

In geometry an edge is a particular type of line segment joining two vertices in a polygon polyhedron or higher dimensional polytope. This expression transfers the edge of a cutting instrument to one s feelings. In the case of a cube it has 12 such edges. Won numerous awards honors.
