The base of any geometric figure is (for polygons) any side that you wish to measure from or (for polyhedra) any face that you wish to measure (or measure from). Bases are most commonly used in geometric formulae for area and volume. It is most commonly represented by the variable b


[edit] Examples

The formula for the area of a triangle:

A=\frac{1}{2}bh\,

where b is the length of the side from which you measure your perpendicular height (h).

The formula for the volume of a cone:

V=\frac{1}{3}Bh\,

the area of cylinder is area of the base times the height of the cylinder

where B is the area of the circular face of the cone.
