triangle pentgon heptagon nonagon etc.
Not true. The base has parallel edges.

Press the 3 buttons on the door (with the jagged edges) and the last button behind the plant on the right. See related link for screenshots.
Two on the top plate and two on the bottom plate. Space them about 3/4" fron the edges.
It is a square based pyramid
A hexahedron has six faces. There are seven topologically distinct convex shapes and three concave ones. The faces can be triangles, quadrilaterals or pentagonal and the number of edges can range from 9 to 12. The number of vertices is 4 fewer than the number of edges.
It has 9 edges, 5 faces and 6 vertices
It is a solid shape with six faces. There are seven topologically distinct convex shapes and three concave ones. The faces can be triangles, quadrilaterals or pentagonal and the number of edges can range from 9 to 12. The number of vertices is 4 fewer than the number of edges.
no numbers have the same number of edges and vertices
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
1~Tetrahedron *4 faces (made of equilateral triangles) *6 edges *5 vertices 2~Hexahedron (cube) *6 faces (made of squares) *12 edges *8 vertices 3~Octrahedron *8 faces (made up of equilateral triangles) *12 edges *6 vertices 4~Icosahedron *20 faces (made of equilateral triangles) *30 edges *12 verticies 5~Dodecahedron *12 faces (made of pentagons) *30 edges *20 vertices.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
Tetrahedron
A sphere- there are no faces, edges or vertices
for any prism , number of ___ + number of vertices = number of edges + ___
There is no limit to the number of vertices nor edges.
