A triangular prism
hexagon base prism
1. triangular prism it has 2 triangular faces. 2.triangular base pyramid, it has 5 triangular faces. 3. square base pyramid, it has 4 triangular faces.
A polyhedron is a 3-dimensional object comprising a space enclosed by a number of polygons. In general, these polygons are called faces: in some polyhedra they are also called bases. They may or may not be triangular. A pentagonal prism, for example, has no triangle face and so no triangular base.
A polyhedron is a 2 dimensional object. To have fasce it would have to be at least 3 dimensional. If you want to know what is a polyhedron with 4 sides, it's a quadrilateral THAT'S NOT QUITE RIGHT - actually it's completely false. Sorry, Ratty, a polyhedron is a 3 dimensional figure. Polygon refers to 2 dimensional figures. A pyramid with a triangular base is a polyhedron with 4 faces.
Triangular Pyrimid
It is a 3-dimensional shape - a polyhedron = whose base is a rectangle and which has four triangular faces attached to its sides. These free vertices of these triangles meet at an apex above the base.
It is a pyramid
That would be a triangular pyramid.
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
A triangular prism is one with two triangles as the bases and 3 corresponding parallelograms as faces. The triangular prism is also a prismatic uniform polyhedron.
