What is the tetrahedron parts names?
The three parts are faces, vertices and edges. The faces are the flat surfaces, the edges are the lines that joint the corners which are called vertices.
Names of 3d shape?
Cube: 6 faces, 12 edges and 8 vertices. Cuboid: 6 faces, 12 edges and 8 vertices. Sphere: 1 Face and no edges or vertices. Cylinder: 3 faces, 2 edges and no vertices. Cone: 2 faces, and 1 edge and vertices. Triangle Pyramid: 4 faces and vertices and 6 edges. Square Pyramid: 5 faces and vertices and 8 edges. Triangle Prism: 5 faces, 9 edges and 6 vertices. Examples, Cube: A box Cuboid: A keyboard Sphere: A ball Cylinder: Can of beans Cone: Ice-cream cone Triangle Pyramid: Bit of a tobarone bar Square Pyramid: Egyptian Pyramid Triangle Prism: Tobarone Bar
What characteristic names a prism?
a prism is a polyhedron with two congruent faces, called bases, that lie in parallel planes. The other faces, called lateral faces, are parellelograms formed by connecting the corresponding vertices of the bases. the segments connecting the vertices are lateral edges. the altitude, or height, of a prism is the perpendicular distance between its bases.
What is another name for a decahedron?
A decahedron is a closed 3-D shape with ten polygonal faces. There are 32,300 topologically different decahdra and, since none of these are regular, the term is ambiguous. Some simple decahedra have names, such as:nonagon-based pyramidoctagon-based prismsquare antiprismpentagonal dipyramid.
What are the names of 3d shapes?
Names of 3D shapes 1 face: sphere 4 faces: tetrahedron/triangle based pyramid 5 faces: pentahedron/square based pyramid 6 faces: hexahedron (sexahedron)/cube/cuboid 7 faces: septahedron 8 faces: octahedron 9 faces: nonahedron 10 faces: decahedron 11 faces: undecahedron 12 faces: dodecahedron 13 faces: tridecahedron 14 faces: tetradecahedron 15 faces: pentadecahedron 16 faces: hexadecahedron (sexadecahedron) 17 faces: septadecahedron 18 faces: octadecahedron 19 faces: nonadecahedron 20 faces: icosahedron 21 faces: unicosahedron 22 faces: dicosahedron ... 29 faces: nonicosahedron 30 faces: tricontahedron 90 faces: ennacontahedron

How many edges on a rectangular sphere?
There is no geometrical object called a rectangular sphere. Objects with similar names include the sphere and the rectangular prism. For example, the 2-sphere is the surface of a ball, with no edges and one face. The rectangular prisms include the cube, the shape of shoe box, and so forth, having eight vertices, twelve edges, and six faces.
3d shape with 15 edges?
pentadecahedron * * * * * No. Even though I do not know the correct answer, I do know that that is not the correct answer. A pentadecahedron has 15 faces - NOT 15 edges. Polyhedra often have names with Greek prefices which refer to the number of faces.
What are the names of the faces on a square based pyramid?
if a square has edges abcd is it necessary to name it in alphabetical order
What are the names of the faces of a triangular pyramid?
NO such thing as a triangular pyramid. A PYRAMID has a square base, upon which four triangles are mounted, to form a peak. A TETRAHEDRON has a triangular base and three triangular faces mounted on it.
Is there another name for a dodecahedron?
A dodecahedron is a generic term which describes a 3-dimensional shape with 12 polygonal faces. There are approx 6.4 million topologically different convex dodecahedra plus concave ones. They can have 8 to 20 vertices and 18 to 30 edges. So there would be around 6.4 million other names!
