In 2 dimensions: a vertex. In 3 dimensions: an edge.
In two dimensions 6 triangles meet at a vertex. In 3-dimensions any number of triangles (greater than 2) can meet at a vertext - a pyramid with the base in the shape of an n-gon will have n triangles meeting at its apex.
how many diagonals from a vertex a heptagon have
4. And the plural of vertex is vertices.
A vertex is a point, so one.
Edges: 2, Vertex: None.
A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
It usually means a straight line going from one vertex of a polygon, polyhedron (or a shape in more dimensions) to another vertex. More generally any line between the 'X' or 'Y' axes on a graph
depends on what shape that vertex is in
0 vertex edges and 1 base.
Three edges meet at each vertex.
n-3 from each vertex.
