Title  Description  

Value  Value is worth as well as numerical equivalence. We can estimate the worth or value of a product or service. The value of pi (π) is constant, and we approximate that value when we express it as a decimal, as 3.14 or 3.14159. 

Velocity  Formally a vector in physics, Velocity has both magnitude (speed) and direction. 

Venn Diagram  Most often graphics of overlapping circles and ovals, a Venn Diagram depicts sets, subsets, and their intersections and unions. 

Vertex  A "corner" of a polygon is a Vertex; an extremum of a conic section is a Vertex; the endpoint(s) of rays that form an angle is a Vertex. 

Vertical  Straight up, perpendicular to horizontal, is Vertical. Vertical lines have an indeterminate or infinite slope. 

Volume  The extent to which an object fills units of threedimensional space is its Volume.
