Tools/Software: Computer with Geogebra Software installed

Procedure:

1. Start the Geogebra Software. Click on Tool No 5 and select ‘Circle with center through point’.

2. Click at any place in the Graphic Area where you want one center ‘A’ of the first circle. Drag your mouse away from the center until you see a circle of appropriate size. Click to get point ‘B’.

3. Click on any point ‘C’ in the graphic area outside the first circle where you want the center of the second circle.Drag outward until the two circles are just touching. Click to get point ‘D’. See

4. Click on Tool No 2 and select ‘Segment between two points’.

5. Click on ‘A’ followed by ’C’.

6. Click on Tool 1 and select ‘Point on Object’.

7. Click anywhere on Segment AC. A New Point ‘E’ will appear where you have clicked.

8. Drag the point ‘E’ till it lies on the point where the two circles touch each other.

10. Click on Point ‘A’ followed by point ‘E’. Click on Point ‘E’ followed by point ‘C’.

Click on Point ‘A’ followed by point ‘C’.

11. In the Algebra Section verify that length(AC) = length(AE) + length(EC). This proves that A-E-C, i.e., the point of contact of two touching circles lies on the line joining their centers.

Result:  The Theorem is verified.

Practical 10

Title: Verification of Inscribed Angle Theorem

Software and Version: Geogebra

Theory: Verify the theorem using Geogebra - The measure of an 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.

Procedure:

1)          Start the Geogebra Software

2)         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.

3)         Using New Point tool, add two other points C and D on the circumference of the circle

4)         Select the Segment between Two Points tool and draw the segments AB, AC, DB and DC.

5)         Select the Angle tool. Click on the segments AB and AC. This measures the angle subtended by the arc CB at the centre as α. Similarly, click on the segments DB and DC. This measures the angle subtended by the arc CB at the circumference as β.

6)         It is seen that α=2β, i.e. the measure of the angle subtended by an arc at the circumference is half that subtended at the centre.

Result: Theorem verified.
