the turtle has the fewest edges
it has 3 faces
No. They have curved edges, so they can't be polyhedra.
Polyhedra.
a sphere has no edgesOf the solids with planar faces and line edges the tetrahedron has the fewest edges and faces. (Four faces and six edges)
The Euler characteristic for simply connected polyhedra isF + V = E + 2 where F = # faces, V = # vertices and E = # edges.
dodecahedron
It applies to simply connected convex polyhedra.
No. Faces + Vertices = Edges + 2 (The Euler characteristic of simply connected polyhedra).
For convex polyhedra it is called the Euler characteristic.This requires that V - E + F = 2where V = number of vertices,E = number of edges andF = number of faces.
They are all polyhedra with 12 edges.
