A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
It is a corner: a point where three of more faces meet.

In a 3-dimensional shape with polygonal faces, an edge is a straight line at which two faces meet. A vertex is a point where three or more edges meet. In solid shapes which are not polyhedra, an edge is still a line - possibly curved - where two faces meet. But a vertex can be any corner, for example, the point of a cone.

In geometry and trigonometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex or vertex of the angle (vertices in plural).With solid figures, like pyramids or polyhedrons, a vertex is a corner where three or more of the faces meet.Remember,* faces are the flat sides.* Edges are the lines where two of the faces meet.* Vertices are the corners where three or more of the faces meet.
It is the vertex and its plural is vertices
That's a "vertex".
