The 20 pages that link to Vertex (geometry), each with the reason it gives.

• Euler characteristicRelated: Vertices provide the zero-dimensional terms in the classical count.

• CircumcenterRelated: The three vertices are the points equidistant from the circumcenter.

• Matching (graph theory)Related: The no-shared-endpoints rule means each vertex belongs to at most one selected edge.

• Interior angleRelated: The two adjacent sides forming an interior angle meet at a polygon vertex.

• ParabolaRelated: It marks the parabola’s turning point and lies halfway between focus and directrix.

• QuadrilateralRelated: Four vertices mark the corners where a quadrilateral’s sides join.

• Convex polygonRelated: Convexity can be checked at the polygon’s vertices through its interior angles.

• Platonic solidRelated: The same number of faces must meet at each Platonic solid vertex.

• TetrahedronRelated: Four vertices are the tetrahedron’s corners.

• Edge coverRelated: An edge cover must include an edge incident to every vertex.

• Internal and external anglesRelated: Each polygon vertex is the common endpoint of the sides forming its angles.
