That is a vertex.
A corner
Three edges meet at each vertex.
Vertex.
Edges join two vertices. Three or more edges meet at a vertex (it could be two if not in a polyhedron).
That is a vertex.
A corner
Three edges meet at each vertex.
A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
A corner where three edges meet is also called a vertex. A vertex can be also used in Algebra 2, in Quadratic Equations.

Edges join two vertices. Three or more edges meet at a vertex (it could be two if not in a polyhedron).
An edge is where two faces of a three dimensional figure meet. An vertex is where three edges meet.
