a cone
That's a sphere.(Actually, any ellipsoid.)
i think it is a cylinder
triangler prism
Two tetrahedron stuck together by a face.
a oval or heart
It is a cube
An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles). A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).
solid-----> 3 dimensionaledge----> the part that's not the side, face, or cornerI was thinking...?...pyramid...?...pentagon...?...idk
it only has one face and has no edges or vertexes and also is circular
The edges of a cube are the parts of a cube when one face of the cube ends and another begins. Not to be confused with the vertexes, which are pretty much like corners.
An irregular blob, an ellipsoid, a sphere, a toroid (doughnut) are some examples.
18. Six on each face, and six more that connect the vertexes of the two faces.
