    • Vertex - math word definition - Math Open Reference
      • Vertex typically means a corner or a point where lines meet. For example a square has four corners, each is called a vertex. The plural form of vertex is vertices. (Pronounced: "ver - tiss- ease"). A square for example has four vertices.

  2. A point where two or more line segments meet. A corner. Examples: • any corner of a pentagon (a plane shape) • any corner of a tetrahedron (a solid) (The plural of vertex is "vertices".) See: Vertex (parabola)

  3. Vertex is a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet. The plural of a vertex is vertices. For example, in the above figures, points A, B, C, D, and E are vertices. History Vertex is part of Euclidean Geometry, first published in a book about Geometry in the late 19th century.

    The vertex of an angle is the common endpoint of two raysthat make up the angle's sides. The vertex for angle BAC, written ∠BAC, is point A. The angle can also be named as ∠CAB or by only its vertex, ∠A. When using three points to name the angle, always put the name of the vertex in the middle. So, ∠BAC is not the same angle as ∠ABC or ∠BCA. Be car...

    The endpoints of each side of a polygonare the vertices of the polygon. The vertices are also referred to as corners of the polygon. Points A, B, C, and D are vertices for the rectangleabove. Polygons can be named by their vertices as long as they are listed in consecutive order. The rectangle above can be named as ABCD, CBAD, or other sequences, b...

    In solidgeometry, a vertex is the point where at least 3 edges meet. One of the vertices of the five-sided polyhedron(pentahedron) above is shown. Notice that the 3 edges displayed meet at the vertex. The pentahedron has a total of 6 vertices. A square pyramid has 5 vertices. In the pyramid above, A, B, C, D, and E are the vertices. Point B is the ...

    Circles do not have any vertices. The central angle of a circle is the angle whose vertex is always the centerof the circle. For the circle with center O above, ∠AOB is a central angle since its vertex, O, is also the center of the circle.

    In analytic geometry, the vertex of the graph of a parabolais the graph's maximum point or minimum point. The vertices for the graphs of the other conic sections are critical points that help define their graphs.
