In geometry, a vertex (pl.: vertices or vertexes) is a point where two or more curves, lines, or edges meet or intersect. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.
For example, in a polyhedron (3-dimensional polytope), a face is a facet, an edge is a ridge, and a vertex is a peak. Vertex figure: not itself an element of a polytope, but a diagram showing how the elements meet.
By considering the connectivity of these neighboring vertices, a vertex figure can be constructed for each vertex of a polytope: Each vertex of the vertex figure coincides with a vertex of the original polytope. Each edge of the vertex figure exists on or inside of a face of the original polytope connecting two alternate vertices from an ...
Vertex (geometry), a point where two or more curves, lines, or edges meet Vertex (computer graphics), a data structure that describes the position of a point Vertex (curve), a point of a plane curve where the first derivative of curvature is zero

Before and after photos of the deadly wildfires in the Los Angeles area have sent tens of thousands scrambling for safety and decimated neighborhoods.

The dots are the vertices of the curve, each corresponding to a cusp on the evolute. In the geometry of plane curves , a vertex is a point of where the first derivative of curvature is zero. [ 1 ] This is typically a local maximum or minimum of curvature, [ 2 ] and some authors define a vertex to be more specifically a local extremum of ...
