Distance between two points

OBJECTIVE

To find the distance between two given points graphically.

PREREQUISITE KNOWLEDGE

Knowledge of plotting on graph paper

Concept of distance formula

MATERIALS REQUIRED

Graph Paper

Pencil

Ruler

PROCEDURE

Draw the axis OX. and  OY. on the graph paper  (Image 1)

Mark two points A(X1,Y1) and B(X2,Y2) on the graph paper

By Image 1  

 

AC=( X2-X1)

BC=( Y2-Y1)

                                                                           Image 1

By Pythagoras theorem

Which can be written as

OBSERVATION

So,the distance between two given points(X1,Y1) and (X2,Y2) is

CONCLUSION

In this way we have Verified the distance formula.

Distance between two points is
