# endpoint

An *endpoint* of a line segment $L$ is a point that belongs to the boundary of $L$. Note that every line segment has two distinct endpoints. For example, if $V$ is a vector space and $a,b\in V$ with $b\neq 0$, then the endpoints of the line segment $\displaystyle L=\{a+tb:t\in[0,1]\}$ are $a$ and $a+b$.

Note that the endpoints of the open line segment $\displaystyle L=\{a+tb:t\in(0,1)\}$ are also $a$ and $a+b$.
