Determine if the properties define a ray or a line segment

Answer :

Ray:⇒

  A ray has one starting point and other end of ray when produced from that point with the help of line segment ,it goes infinitely in that direction in which it is produced.The other end is not fixed.

For example: Take star as a point in space .From there infinite number of rays originate which goes in many direction.So, it has a starting point that is where the star is located and we can't find other end.

Take example of Electric Bulb.Considering it as a point,you can observe that infinite number of rays(Combination of a point and Infinite line segment) originating from that electric bulb.The Point is Bulb.

Line Segment : ⇒

    A line segment has both end fixed.It is of finite length.For example, Height of any Human measured in feet,cm or inches is an example of line segment.Diameter of sun is line segment.
