The prisms are polyhedrons that have two parallel and equal faces called bases and their side faces are parallelograms. The main elements of a prism are:
Next let's see the different types of prism that exist.
Regular prisms
The regular prisms are those which bases are regular polygons.
Irregular prisms
The irregular prisms are those which bases are irregular polygons.
Straight prisms
The straight prisms are those which side faces are rectangles or squares. Namely all the regular prisms are straight prisms, although not all the straight prisms are regular. We can do the say same with the irregular prisms, since all the regular prisms are straight prisms, although not all the straight prisms are irregular.
Oblique prisms
The oblique prisms are those which side faces are romboides or rhombuss.
Parallelepipeds
The parallelepipeds are those prisms which bases are parallelograms.
Cuboid
The cuboids are prisms that have all of its faces rectangular.
