  6. Definition of the math word edge - Math Open Reference

    In any geometric solid that is composed of flat surfaces (faces), an edge is a line segment where two such surfaces meet. For example, the cube above has six surfaces (faces), that are squares.

  7. Edge (geometry) explained

    What is Edge (geometry)? Edge is a particular type of line segment joining two vertices in a polygon, polyhedron, or higher-dimensional polytope.

  8. Edge - Meaningful Math

    In 3D shapes, an edge is a line segment where two faces meet, helping to define the shape’s structure. Edges help students see how shapes are formed and how parts of a figure connect. …

  9. Edge Definition - Pre-Algebra Key Term | Fiveable

    An edge is a line segment that connects two vertices in a geometric shape. It is the boundary between two adjacent faces or surfaces in a three-dimensional object.

  10. Edges in Math | Definition, Identification & Examples - Study.com

    In math, edges are the lines that connect corners or surfaces. On flat polygons, the edges are often called the sides. On solid polyhedrons, the edges are the places where surfaces meet.
