Vertex.
A vortex is an area of circular fluid flow in fluid dynamics and no edges meet there. A vertex is a corner of a geometric shape and there can be two or more edges meeting at a vertex. There is no upper limit to the number of edges.
A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
A shape with more than 12 edges is a dodecahedron which has 30 edges
A 4-sided pyramid, also known as a square pyramid, has 8 edges. This is the more-common shape for pyramidal structures. There are 4 edges where the triangular sides meet each other, and there are 4 more edges where the 4 triangular sides meet the square base.
A shape with seven edges is a polygon, more precisely it is called a heptagon.
Three dimensional objects have edges, vertices and faces. A face is a plane surface which forms a boundary of the shape. Two faces meet along a line which is an edge. Three or more faces meet at a point which is a vertex.
Vertice.
yes it is
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.
A circle.
