Line, line segment and rays

l Line is a straight path and extends in both direction without end A line through two point A and B is written as Also it is denoted by letter l Since line has not end points we cannot find its length. The following are not lines since they have not straight path AB or BA

Example :- Identify the lines from the figure We can see 3 lines from the figure Line L1 Line L2 Line L3 or AB or BA or CD or DC or PQ or QP

Line segment is a line that ends at both side. We use capital letter to denote end of line segment. In the above figure the line segment has two end point A and B. A line segment with end points A and B is written as Since line segment has end points, we can measure its length AB or BA

Example :- Identify the line segment from the figure We can see 4 line segments from the figure Line AB or BA BD or DB CD or DC AC or CA

A ray with end point A and passes through point B is written as Rays is a line that ends at one side and extends at other side without end. A B A ray with end point A and passes through point B is written as Since ray does not have two end point, it length cannot be measured. AB

Example :- Identify rays from the figure We can see 3 rays from the figure Ray OA OB OC
