A specific position or location on the surface of the plane is referred to as a point.

The above figure shows points

$A$ and

$B$ .

A point is an invisible dot that may determine a location/position but can not be extended. To represent the location/position, we label each point using an English alphabet.

Example:

We are planning to locate the five places (let them be

$A$ ,

$B$ ,

$C$ ,

$D$ and

$E$ ) on a map using the concept of points and label them accordingly.

When a line is drawn between two points, it is referred to as a line segment.

The above figure shows a line segment

$AB$ and is represented as

$\bar{AB}$ .

Important!

A line segment is used to determine the distance between two points.

Example:

We are planning to demonstrate the distance between the five places (let them be

$A$ ,

$B$ ,

$C$ ,

$D$ and

$E$ ) on a map using the concept of a line segment and label them accordingly. Here the distance between

$A$ and

$B$ is shown by drawing a line between

$A$ and

$B$ . Similarly, the distance between

$B$ and

$E$ , and the distance between

$C$ and

$D$ are shown in the following picture.
