endpoint (original) (raw)

.aa+b

Note that the endpoints of the open line segment L={a+t⁢b:t∈(0,1)} are also a and a+b.

.aa+b

Endpoints can be defined in a manner for other geometric . These include rays, arcs (http://planetmath.org/PathConnected), and intervals (http://planetmath.org/Interval).

• •
  Rays have one endpoint.
• •
  have two endpoints.
• •
  can have zero, one, or two endpoints, depending on whether they are bounded above and/or below. See the entry on intervals (http://planetmath.org/Interval) for more details.
