 # Line Segment And Ray

We come across many shapes in daily life. Consider a triangle, a square or any other shape. To draw any of these figures, one begins with a line or a line segment or a curve. Depending upon the number and arrangement of these lines we get distinct types of shapes and figures. For example, a triangle is a figure enclosed by 3 line segments, Pentagon is a polygon bounded by 5 line segments and so on.We have already discussed line now let us see what is line segment and ray.

LINE SEGMENT

A line segment is a part of a line having two end points. Figures such as a triangle, polygon, hexagon, square are made of different numbers of line segments .The measure of a line segment is called its length.  In contrast to infinitely extending line, a line segment has a fixed length and can be measured easily. A line segment with A and B as two end points is represented as $\overline{AB}$. RAY

Ray is another part of a line. It is a combination of a line and a line segment which has an infinitely extending end and one terminating end. As its one end is non-terminating, its length cannot be measured. A ray is represented by $\overrightarrow{BA}$  where one end is symbolized by an endpoint and the infinitely extending part by an arrow.
