What is the vertex of an angle?

The video tutorial explains the concept of a vertex in geometry, focusing on its role as the endpoint where two rays meet to form an angle. It describes how rays extend to infinity and how the vertex is the point of rotation for measuring angles. The tutorial also differentiates between the initial and terminal sides of an angle, emphasizing the importance of the vertex in understanding angle formation and measurement.
