Vertex
A vertex is the point where three or more edges of a solid figure meet.
A vertex.
I'm waiting for the answer
polygon
Three edges meet at each vertex.
A pyramid is a generic term, used to describe a three dimensional shape with a polygonal base and triangular sides that meet at an apex above the base. The base can be a polygon with any number of sides and the number of faces, edges and vertices of a pyramid depend on this number of sides. If the base is an n-sided polygon, then the pyramid has 2n edges.
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.
