The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments and lines that result in two straight "sides" meeting at one place.

Understanding the Concept of a Vertex
The term "vertex" is crucial in geometry, especially when discussing angles formed by the meeting of lines, line segments, or rays.
What is a Vertex?
- A vertex is defined as the point where two lines, line segments, or rays converge.
- It acts as the "corner" of an angle, indicating the position where the angle opens.
Components of Angles
- Lines and Rays: These are the two components that create an angle. When two lines intersect, they form different angles at the vertex.
- Angle Formation: The space between the two lines or rays, measured in degrees, is what we refer to as an angle.
Importance of the Vertex
- Identifying Angles: The vertex helps in identifying and naming angles. For instance, in angle ABC, B is the vertex where lines AB and BC meet.
- Geometric Concepts: The concept of a vertex is foundational in various geometric principles, including polygons and polyhedra.
Conclusion
In summary, the correct answer to the question is option 'B', as a vertex is indeed the point at which two lines or rays meet to form an angle. Recognizing the vertex is essential for understanding basic geometric shapes and their properties.
