It could be called a pentahedral prism.
a triangular prism has to triangular bases while a rectangular prism has a rectangle as the bases.
A triangular prism
Triangular Prism
A triangular prism has triangular bases, a heagonal prism has ... you guessed it! ... hexagonal bases.
None. By definition, a triangular prism has triangular bases. If it had circular bases it would be a circular prism (cylinder).
Assuming that pirsim is meant to be prism, the answer is that a triangular based prism has triangular bases!
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
A triangular prism always has 5 sides. It has two triangular bases and 3 rectangular faces. If the bases are not congruent it is called an oblique prism.
A prism with nine edges is called a triangular prism. In general, a prism is named based on the shape of its base; a triangular prism has two triangular bases and three rectangular lateral faces, resulting in a total of nine edges. Each triangular base contributes three edges, and three additional edges connect the corresponding vertices of the two bases.
A triangular prism has 2 bases on it!
The parallel bases would be the two triangular faces, on either end of the prism.
A polyhedron with two identical parallel polygon-shaped bases is called a prism. The sides of the prism, which connect the corresponding edges of the two bases, are parallelograms. The shape of the bases determines the type of prism; for example, a prism with triangular bases is called a triangular prism, while one with rectangular bases is a rectangular prism. Prisms are characterized by their uniform cross-sections along their height.
