A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
15 edges
A Platonic solid is a regular, convex polyhedron. The same amount of edges must meet at each vertex, all the faces need to be uniform, and all the dihedral angles must be the same.

A pyramid
Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.
Yes. I think of an edge as a line. The edges meet at vertices, and the faces meet at edges.
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.
The corner of a solid where two faces meet is called a "vertex." In three-dimensional geometry, a vertex is a point where edges converge, and it is one of the key elements in defining the shape of a solid. For example, a cube has eight vertices.
No such shape exists. the closest contenders would be: a cylinder - 3 faces, 2 edges, 0 verticies or a cone - 2 faces, 1 edge, 1 vertex
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.
a vertex
A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
The platonic solid that has pentagons for faces is the dodecahedron. It consists of 12 regular pentagonal faces, 20 vertices, and 30 edges. The dodecahedron is one of the five Platonic solids, which are characterized by their faces being congruent regular polygons meeting at each vertex.
No such thing A tetrahedron is a polyhedron composed of four triangular faces, three of which meet at each vertex. Similar to a pyramid but with a triangular base.
a cylinder has 2 faces and 2 edges. :)
That is the Vertex
From Wikipedia:A Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex. Moreover, all its edges are congruent, as are its vertices and angles.
A tetrahedron has four faces and six edges.
