Practical Name: Verify the theorem using
GeoGebra. If two circles are touching circles then the common point lies on the
line joining their centres.
Software used: Computer, Geogebra
software.
Procedure : 1) First Select the Cirlce with Centre through Point
tool .Let the centre of the
circle be
point A and move the cursor so that point B lies in a convenient
position .
2) Then Select the Circle with
centre through Point tool. Let the
centre of the circle b.
3) Construct the segments AC
connecting point A and C using the segment between two
Point tool.
Result/Output: It can be noticed that the common point lies
on the line joining their centers

Practical Name: Verify the theorem using
GeoGebra. The measure of an angle subtended by an arc on the circle is half of the measure of the anglesubtended
by the
same arc at the
centre.
Software used: Computer,
Software (GeoGebra)
Procedure: 1) Select
the ‘Circle with centre through Point tool’. Click at a point A and then
click at another
convenient point B to draw a circle with centre A through point B.
2) Using the New point tool, add two
other points C and D on the circumference of the circle.
3) Consturct the
segments AC, AB, CD and DB by connecting points A, B, C, D respectively using
the segment between two point tool.
4) Select the Angle
tool. Click on the segments AB and AC. Similarly click on the segment DB and DC.
Result/Output: It can be noticed that
the measure of the angle subtended by an arc at a point
on the circle is half of the measure of the angle
subtended by the same arc at
the centre.

Practical Name: find the mean, median,
mode of the following data 11,25,28,37,65,47,58,59,78,14.
Software used: Computer,
Software (GeoGebra)
Procedure: 1) In the Input
bar, type Mean[11,25,28,37,65,47,58,59,78,14] and press
the
enter key. The result of mean will be displayed in the algebra window.
2) Repeat the first step and type Median[11,25,28,37,65,47,58,59,78,14]
Input box. The result of median will be displayed in the algebra window.
3) Again repeat the first step and type
Mode[11,25,28,37,65,47,58,59,78,14] Input box. The result of mode will be
displayed in the algebra window.
Result/Output: The result of mean median mode will be displayed in the algebra
window

Practical Name: Construct a regular
polygon with 6 sides using "polygon" tool.
Software used: Computer,
Software (GeoGebra)
Procedure:
1) Open GeoGebra software , right click on the screen, Click on Axes option
to get the clear screen.
2) Select the Circle with Centre through Point tool. Click at a point A and another suitable point B to draw a circle c with centre A through point B.
3) Similarly, draw a circle d through with centre B through point A
4) Intersect the circle with the Intersect Two Objects tool to get the hexagon's vertices C and D
5) Draw a circle with centre C through point A, and centre D through point A
6) Click at the intersection of the circles c and e to get the vertex E and at the intersection of the circles c and f to get the vertex F
7) Using a New point tool, click on the circle to get the vertex G
8) Select the Polygon tool and click on the vertices, other than A,
9) Slect the Angle tool and click inside the hexagon.
Result/Output: We will get a regular polygon with the segment value given on the
hand side.
