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 $\overline{\mathit{AB}}$.

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.
