At the end of the answer, you can see an image with each type of figure, and the definition for each.
Sadly, the image is not uploaded, so I will give a general answer.
A line BC is just a line that passes through two points, B and C, and it extends infinitely in both ways.
A ray BC is a figure that starts at B, passes through C, and extends infinitely.
A segment BC is a line that starts at B and ends at C.
In the image below there are examples of these 3 figures.
First, we have the segment AB, then the line CD, and then the ray EF.
