A Line Segment
Take a piece of paper of any size and fold it as you wish.
Upon unfolding it, what do we see? This gives the idea of a
Line Segment AB
Let's look at the another example.
Take a random piece of string or a thread and hold it up to view it. This is another live example of a line segment being formed.
Holding a piece of string
Look Around you. Give some examples of models representing a line segment.
Edge of a box
Edge of a photographs/postcards
On the canvas to the side we have marked two points and connected them with a line.
Now, try to connect A to B by all possible routes and see if you can connect with a shorter length.
How many ways could you join?
As it turns out, the shortest joining of point A to B (including A and B) is ,in fact, a line segment.
It is denoted by AB or BA.
Here, the points A and B are called the endpoints of the segment.
Similarly, we can use a thin thread. If we hold a section of the thread with our hands and make sure that it is stretched without a slack, this again represents a line segment.(Refer to the above image)
The ends held by hands are the end points of the line segment in this case.
Below, select any two random points and join the points to make a line segment.
