How many rays can be drawn with a given point as the initial point?

In the given diagram $\mathrm{M}$ is a point on ray $\overrightarrow{\mathrm{NQ}}$.

Consider the line $\overleftrightarrow{\mathrm{PQ}}$ given below. $\mathrm{L}, \mathrm{M}, \mathrm{N}$ are points on line segment $\overline{\mathrm{LN}}$.

Every ray has a finite length.

The line $\overleftrightarrow{\mathrm{AB}}$ is the same as the line $\overleftrightarrow{\mathrm{BA}}$.

Two intersecting lines intersect at a point.

If points $\mathrm{A}, \mathrm{B}, \mathrm{C}$ are collinear and points $\mathrm{C}, \mathrm{D}, \mathrm{E}$ are collinear then the points $\mathrm{A},\mathrm{B},\mathrm{C},\mathrm{D},\mathrm{E}$ are collinear.

A _____ has a definite length. $($line$/$line segment$)$

A ray has _____ endpoint. (two/ one)
