Point

A specific position or location on the surface of the plane is referred to as a point. It has no length, breadth or thickness.

The above figure shows point

$A$ and

$B$ .

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

Example:

We plan to locate the five-place (let them be

$A$ ,

$B$ ,

$C$ ,

$D$ and

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

Line segment

A line segment is the shortest distance between two points. It is also a part of the line. Name the line segment using its two endpoints.

The above figure shows a line segment

$PQ$ and is represented as

$\overline{PQ}$ .

Example:

We plan to use the idea of a line segment to illustrate the distance between the places (let's call them

$A$ ,

$B$ ,

$C$ and

$D$ ) on a map and label them accordingly.

When we connect points

$A$ and

$B$ , we get the line segment

$\overline {AB}$ .

Also, if we connect the points

$C$ and

$D$ , we get the line segment

$\overline {CD}$ .

We can calculate the distance of

$\overline {AB}$ and

$\overline {CD}$ using measurements.
