When two rays meet at a common endpoint, an angle is formed.
A vertex, or as a whole, an angle.
That's the angle's "vertex".
vertex
< the point where the two rays meet is called a vertex.

An angle.
I am the endpoint where two sides of a polygon meet?
A vertex, or as a whole, an angle.
Lines don't have endpoints, they extend indefinitely. Two line segments with a common endpoint form an angle.
That's the angle's "vertex".
The vertex
Two collinear rays with the same endpoint form an angle. They share a common initial point and extend in opposite directions. The endpoint where they meet is called the vertex of the angle.
vertecies/vertex.
If I understand your question, you are referring to the vertex. This is the point where the sides meet, also where the angle is formed.
