   What is a vertex in geometry?

   • The concept of vertex forms the basis of explaining many advanced concepts of geometry. A line segment is a part of a line. A ray is a line segment that we can extend indefinitely. When two line segments or rays meet, they form an angle. By definition, when two lines meet to form an angle, a vertex is formed.

   What is a vertex in a quadratic equation?

   • In a quadratic equation, this point is called the vertex! Take a look at the vertex of a quadratic equation by watching this tutorial. What is a Quadratic Function? You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown.

   What is an example of a vertex?

   • 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. Vertex is part of Euclidean Geometry, first published in a book about Geometry in the late 19th century.
