parallel
A prism. The name of the prism usually reflects the polygonal shape of the bases eg triangular prism or rectangular prism.
n+2. The sides will compose all the planes perpendicular to the two bases of the prism.
the altitude of a prism is a segment perpendicular to both bases whose endpoints are in the planes of the bases.
Altitude
The answer is 13- for more detail:
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.
Sometimes,only because,a rectangular prism has two bases and four faces, but a triangular prism has two bases and three faces.
a pentagonal prism has 2 bases
A pentagonal prism has 5 planes of symmetry. This is because it can be divided into 5 identical sections by planes passing through the center of the prism and perpendicular to its bases. Each of these planes divides the prism into two equal halves that are mirror images of each other.
A prism will always have at least TWO bases
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.
It can, but need not. Only a right prism must.
