An angle
The vertex
Angle
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
The common endpoint of 2 rays that form an angle is the vertex.

Two rays that share an endpoint form an angle.
An angle is the union of two rays with a common endpoint.
