Introduction
Geogebra is an interactive geometry , algebra, statistics and calculus application, intended for learning and teaching mathematics from primary school to university level. Geogebra’s tools enable us to produce new objects using pointing device. They can be activated by clicking on the corresponding buttons of the Toolbar. This application is free and licensed under the GNU Public License.
ICT Competency
Educational application and relevance
Geogebra is an outstanding technology tool that improves mathematics education.Through simulations, students create concrete representations of geometric theorems instead of abstractly configuring images in the mind. Geogebra is an exciting, Web based application that eliminates concept of memorization. In addition to this, students transform from passive classroom observers to active, excited participants. Meaningful learning occurs as the students manipulate and test data with-in the Geogebra.
Version
The GEOGEBRA version - 5.0.236.0-3D…..
Geogebra is part of the Ubuntu distribution (in the training). This can be opened from Applications → Education → Geogebra.
Configuration
There is no specific configuration for this tool or application.

Development and community help
Working with the application
Functionalities
The tool has several features...like….,
- We can create special .ggb files which can be used to apply a style to other files.
- We can load a .ggb file into another.
- Opacity for lines and perimeters of shapes.
- Insert image tools now supports SVG files.
- This is a simulation as well as graphic plotter

| Step 1 - In GeoGebra you can animate the geometric figure you have drawn and dynamically see how some values like length, area, perimeter of a figure changes, see the same figure in different ways. For detailed resources on how to learn Geogebra you can click on http://karnatakaeducation.org.in/KOER/en/index.php/Portal:ICT_Literacy. | Step 2 - Drawing points, line segment and rays
Select Point Tool, and click anywhere on the drawing point to plot six points A, B, C, D, E, F. |
 Image
|
 Image
|
| Step 3 -
Drawing line segments and lines i. Select Segment between two points tool, click o on point A and then point B. Select Line through two points tool, click on point C and then point D. |
Step 4 - Select Ray through two points tool, click on point E and the point F. |

|
 Image
|
| Step 5 -
Can you describe in your own words the difference between a segment, line and ray? Also see the algebra view and observe the equations of the line b and ray c. The line segment a is represented in the algebra view as a = 2.83, where 2.83 is the length of the segment. |
Step 6 - ii. Drawing a parallel line
iii. Select Point Tool and click anywhere on the drawing point to plot three points A,B, C. iv. Select Line through two points tool, click on point A and then point B. v. Select Parallel Line tool, click on point C first. Then click on line AB. Now use the Move Tool and move points A, B and C. What do you observe? Describe it. Next with Move Graphics view tool and move the drawing pad. Do the two lines ever meet? |

| Step 7 - Rotate a ray
Draw line segment AB of any length (Segment between two points tool). Select the Ray Through two points tool, click on point A, then select another point C on the drawing pad as shown in the figure. Select the Angle tool, as seen in the figure and click on points B, then A and finally C. You will see an angle measure. Click on the Move tool and move point C. |
Step 8 - Start your drawing by using the tool Segment with Given Length from Point. |

|
| Step --- Continue | Step 10 - Continue by drawing the right angle. Do this by drawing a perpendicular line through point A. Choose the perpendicular line tool, click on point A first and then on the line. |
