Term
prism
Definition
a three-dimensional figure in which 2 faces are congruent polygons in parallel planes
Term
base
Definition
2 faces that are congruent polygons in parallel planes
Term
lateral face
Definition
faces of the prism that connect the bases
Term
height or altitude
Definition
distance between the two bases of a prism
Term
non-prism
Definition
a three-dimensional figure which does not fulfill the requirements of a prism - these figures may have two bases, one base, or no base at all
Term
cross-section
Definition
when we take a "slice" through it and the result is a two-dimensional figure
Term
solid of revolution
Definition
if we rotate a two-dimensional figure about one of its sides, the result is a three-dimensional figure
Term
surface area
Definition
the sum of all of the areas of all of the two-dimensional faces
Term
surface area (triangle)
Definition
A=(1/2)bh
Term
surface area (parallelogram)

surface area (square)
Definition
A=s^2
Term
surface area (trapezoid)
Definition
A=(1/2)(base+base)h
Term
volume
Definition
the number of cubic units that fit inside the figure
