Base (geometry) - Citizendia

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). In Geometry a polygon (ˈpɒlɨɡɒn ˈpɒliɡɒn is traditionally a plane figure that is bounded by a closed path or circuit Bases are most commonly used in geometric formulae for area and volume. Area is a Quantity expressing the two- Dimensional size of a defined part of a Surface, typically a region bounded by a closed Curve. The volume of any solid plasma vacuum or theoretical object is how much three- Dimensional space it occupies often quantified numerically It is most commonly represented by the variable $b$

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 ( $h$ ). A triangle is one of the basic Shapes of Geometry: a Polygon with three corners or vertices and three sides or edges which are Line

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.
