In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used in constructing another polyhedron.
The same shape is also called the tetrakis triangular prism, [1] tricapped trigonal prism, [2] tetracaidecadeltahedron, [3] [4] or tetrakaidecadeltahedron; [1] these last names mean a polyhedron with 14 triangular faces. It is an example of a deltahedron, composite polyhedron, and Johnson solid.
An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...
The orthogonal projection of a 3-3 duopyramid. The dual polyhedron of a 3-3 duoprism is called a 3-3 duopyramid or triangular duopyramid. [6], page 45: "The dual of a p,q-duoprism is called a p,q-duopyramid."</ref> It has 9 tetragonal disphenoid cells, 18 triangular faces, 15 edges, and 6 vertices.
Photograph of a triangular prism, dispersing light Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different angles. [1]
In chemistry, the tricapped trigonal prismatic molecular geometry describes the shape of compounds where nine atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triaugmented triangular prism (a trigonal prism with an extra atom attached to each of its three rectangular faces).

In particular, h = 0 at the limits n/d = 6 and n/d = 6/5, and h is maximized at n/d = 2 (in the digonal cupola: the triangular prism, where the triangles are upright). [ 1 ] [ 2 ] In the images above, the star cupolae have been given a consistent colour scheme to aid identifying their faces: the base { n / d } -gon is red, the base {2 n / d ...
Displacement is the shift in location when an object in motion changes from one position to another. [2] For motion over a given interval of time, the displacement divided by the length of the time interval defines the average velocity (a vector), whose magnitude is the average speed (a scalar quantity).
