Polyhedron

solid formed by polygons


face

flat side of a polyhedron


edge

intersection of two faces


vertex

intersection of 3 or more faces


regular polyhedron

only if each face is a regular polygon, each face is congruent to the other faces, faces meet at the vertex at the same way, then it is regular polyhedron.


prism

two faces are the bases that are congruent and parallel ploygons. it has lateral faces which are parallelograms


right prism

lateral edges are perpendicular to the bases


oblique prism

not a right prism


altitude

any segmenent that is perpendicular to the bases (height)


great circle

half a the base of a hemisphere


axis

connects the centers of the bases of a cylinder


the volume of a prism or cylinder is

base area times hieght
