**SSC BOARD EXAM ICT Practical P7 - Using Geogebra draw Draw a line segment of length 6.5 cm and draw perpendicular bisector to Line segment.****Practical Name:**Using Geogebra draw

ii) Draw an angle with measurement 133 and
bisect it.

**Tools/Software:**Computer with Geogebra Software installed.

**Procedure:**

**Using Mouse**

1)
Start the Geogebra Software

2)
Click down arrow on Tool No 2 and
select “Segment with Fixed Length.” Click anywhere in the Graphics view, it
adds a start point A of the Segment and opens a dialog box.

3)
In the dialog box, enter
the length as 6.5 and click the OK button

4)
A horizontal segment {a} of required length will be
drawn.

5)
Select
the Midpoint or Center tool and click on the segment a to add the midpoint C.

6)
Click
on Tool No 3 and select Perpendicular Bisector" Tool and click the segment
{a}, a perpendicular bisector line {b} will be created.

7)
Select the Angle tool.
Click on the segment a and line c, an angle between them as Î± = 90° will be shown.

**Using keyboard:**

1)
Start the Geogebra Software

2)
Click on Input box

3)
Type
the commands in the input box as given below:

A=(2,3)

B=(8,3)

Segment(A,B)

PerpendicularBisector[A,B]

Angle[a,b]

**Draw an angle with measurement 133 and bisect it.**

1)
Select the Segment between two points tool and click at any
two points (horizontally) in the Graphics View. This adds two points, A and B
and the segment {a}.

2)
Click on Tool No 7 and select
‘Angle with given size’.

In the Graphic area click on point A and then the point B. In the box that comes up enter the measure of the angle that you want e.g., 133

In the Graphic area click on point A and then the point B. In the box that comes up enter the measure of the angle that you want e.g., 133

^{o}and click on OK button.
3)
The angle Î± =133

^{o}will be drawn.
4)
Select ‘Segment through two
points’. Click on the points B followed by A', segment {b} will drawn.

5)
Select Tool 3 and click on ‘Angle
Bisector Tool’.

6)
Click on points A followed by B and
A’. The required angle bisector line {c} will be drawn.

7)
Save and print your file if
required.

**Result:**The figures i) and ii) are drawn.

Figure
No. (i)
