A line segment has end points.

Take any points $A, B, C, D and E$ in such a way that no three points are collinear.

Join them in pairs and answer the following:

Name all the points that can be drawn by joining two points at a time.

The length of a line is measurable.

Take any points $A, B, C, D and E$ in such a way that no three points are collinear.

Join them in pairs and answer the following:

How many of the points pass through $D$ if the lines can be drawn joining two points at a time? 

The number of points on a line segment is finite. 

Mark three non-collinear points $\mathrm{A}, \mathrm{B}, \mathrm{C}$ as shown. Draw lines through these points taking two at a time. Name the lines. How many such different lines can be drawn?

Take any points $A, B, C, D and E$ in such a way that no three points are collinear.

Join them in pairs and answer the following:

How many lines can be drawn joining two points at a time?

Infinite number of lines can pass through two given points.

A point $C$ is said to lie between the points $A$ and $B$ if

A ray extends indefinitely in both directions.

Take any points $A, B, C, D and E$ in such a way that no three points are collinear.

Join them in pairs and answer the following:

How many of the points pass through $A$ if the lines can be drawn joining two points at a time? 

The number of ray(s) starting from one given point and passing through another fixed point is:

What do you mean by collinear points? How many lines can you draw passing through three collinear points?

A ray has definite length.

The number of planes passing through $3$ non-collinear points are
