A vertex of an angle is the endpoint where two lines or rays come together. 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. [1] [2] [3]
In geometry, the nonconvex great rhombicosidodecahedron is a nonconvex uniform polyhedron, indexed as U 67. It has 62 faces (20 triangles, 30 squares and 12 pentagrams), 120 edges, and 60 vertices. [1] It is also called the quasirhombicosidodecahedron. It is given a Schläfli symbol rr{5 ⁄ 3,3}. Its vertex figure is a crossed quadrilateral.
In geometry, the great icosicosidodecahedron (or great icosified icosidodecahedron) is a nonconvex uniform polyhedron, indexed as U 48. It has 52 faces (20 triangles, 12 pentagons, and 20 hexagons), 120 edges, and 60 vertices. [1] Its vertex figure is a crossed quadrilateral.
The graph obtained from a squaregraph by making a vertex for each zone (an equivalence class of parallel edges of quadrilaterals) and an edge for each two zones that meet in a quadrilateral is a circle graph determined by a triangle-free chord diagram of the unit disk. [2]
A quadrilateral is a square if and only if it is any one of the following: [2] [3] A rectangle with two adjacent equal sides; A rhombus with a right vertex angle; A rhombus with all angles equal; A parallelogram with one right vertex angle and two adjacent equal sides; A quadrilateral with four equal sides and four right angles
In geometry, a vertex arrangement is a set of points in space described by their relative positions. They can be described by their use in polytopes . For example, a square vertex arrangement is understood to mean four points in a plane, equal distance and angles from a center point.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
In geometry, the rhombicosahedron is a nonconvex uniform polyhedron, indexed as U 56. It has 50 faces (30 squares and 20 hexagons), 120 edges and 60 vertices. [1] Its vertex figure is an antiparallelogram.
