Because in math the definition for vertex is !the point of a geometric figure that is opposite the base. So in this case, the point is the vertex.
the vertex of the angle is the point
The vertex angle is connected to the vertex point
A cone only has 1 vertex because it only has one point where it connects. (vertex=a point)
The concept of a vertex, which is the intersecting point between two or more geometrical shapes, is meaningless in this case. A point can't have a vertex since it has no shape. A vertex, however can be a point. For example, if one 2-D line intersects another 2-D line, that point of intersection is the vertex.
It all depends on what xyz is. If xyz is an arc of a curve, there will be no vertex whereas if xyz is a triangle, each of x, y and z will be a vertex.

The vertex, or maximum, or minimum.
Vertex
A point is a vertex

If the arrows of the graph point down, then the vertex is a maximum because it is the greatest point on the graph. If the arrows point up, then the vertex is the minimum because it is the lowest point.
