Question

define line segments​

Answer 1

Definition of Line Segments :

${ }$

• A line segment has two definite endpoints in a line. The length of the line segment is fixed, which is the distance between two fixed points. The length here can be measured by metric units such as centimeters (cm), millimeters (mm) or by conventional units like feet or inches.

${ }$

Symbol of Line Segment :

${ }$

• A line segment with two endpoints A and B and is denoted by the bar symbol $\sf{(\:—\:)}$ such as $\:\sf\overline{AB}\:$ A line is usually represented by$\:\leftrightarrow\:$ and a ray by a right arrow $\sf{(\rightarrow)}$

${ }$

Line Segment Formula :

${ }$

• As we know, a line segment has two endpoints. Now if we know the coordinates of the endpoints, then we can calculate the length of the line segment by distance formula.
