A vertex, or as a whole, an angle.
the vertex :)
When two rays meet at a common endpoint, an angle is formed.
An angle is a geometric figure formed by two rays that share a common endpoint.
The common endpoint of 2 rays that form an angle is the vertex.
Opposite rays are rays that share the same endpoint (have a common endpoint), but they also form a line.Not always.

An angle.
An angle is a geometric figure formed by two rays that share a common endpoint.
A figure that is made up of two noncollinear rays with a common endpoint is an angle. The angle that is formed can be acute, right, obtuse or reflex.

An angle is formed by two rays with a common endpoint.
An angle or a vertex.
an angle precisely defined as the common endpoint of two rays
An angle is the union of two rays with a common endpoint.
