Practical Name: a) Draw a line segment of length 6.60m and draw perpendicular

                     bisector to line segment.

Software used:  Computer, Software (GeoGebra)

Procedure:1)  Open the GeoGebra, go to the view menu and click on the axes option to get the clear screen.

2)         Select the option Segment with given length from point tool and Click anywhere in the Graphics View.

3)         Now Click on the Screen, a point A will appear with a pop up box asking for the length to be entered. Enter the given value i.e 6.5 cm and then press OK button.

4)         You will get the line segment of the given length.  Now to draw the perpendicular bisector to the line segment, select the Perpendicular bisector tool.
