Which statement explains the difference between a point and a vertex?

The term point presents the lowest level of abstraction in geometry, an entity that has a location in space or a plane but no extent. The term vertex means a corner of · an angle: the point where two line segments join or meet, where two lines cross (intersect), or any appropriate combination of rays, segments and lines that result in two straight “sides” meeting at one place. · a polygon: any point on the polygon where two sides (line segments) meet and connect. · a polyhedron: any point where three or more edges meet and connect to each other. The edges are the connections (line segments as shared sides) of two or more faces (polygons). · for curves a vertex is a point on the curve with a local minimum or maximum of curvature. In SALOME most 2D and 3D objects can be defined through a number of vertices.
