Cabri Geometry is a commercial interactive geometry software produced by the French company Cabrilog for teaching and learning geometry and trigonometry. It was designed with ease-of-use in mind.

The program allows the user to animate geometric figures, proving a significant advantage over those drawn on a blackboard. Relationships between points on a geometric object may easily be demonstrated, which can be useful in the learning process.

There are also graphing and display functions which allow exploration of the connections between geometry and algebra. The program can be run under Windows or the Mac OS.

Cabri II Plus is a dynamic geometry software solution that comes in handy for both math teachers and students. Providing you with a virtual learning environment, this interactive tool can assist you in learning high-level math concepts.

The learning curve is smooth and students can also use the built-in assistant to learn how things work. You can use Cabri II Plus to draw and manipulate all sorts of geometrical figures, from simple lines, circles or triangles to complex 3D shapes.

Create intersection points, add lines, segments, vectors or polygons, circles and arcs. The program allows you to build the geometrical structure by automatically generating perpendicular or parallel lines, drawing angle bisectors or measure angles using the virtual compass.

You can freely manipulate objects, make conjectures and perform calculations. The application can be used for solving symmetry, reflection and translation problems, rotate objects, measure areas, distances, lengths and angles and solve

equations.

Cabri II Plus eases the learning process, as students can add labels to their figures, define and evaluate expressions, mark angles and attach pictures to their drawing. Furthermore, the program allows you to easily draw graphs for different functions, as well as display loci of points or objects.

The software comes with a fully customizable appearance, enabling you to change text style and use the dynamic palette to adjust the object colors. In addition to this, it can easily record a session as you use the program, a feature that comes in handy mostly for teachers.

The figures you create can be transferred to TI graphing calculators or exported to Word and PowerPoint documents.

Overall, Cabri II Plus is a great replacement for the traditional pen and paper, allowing students to with pencil, paper, ruler, and compass! Cabri II Plus offers a wide range of powerful, easy-to-use features. You can draw and manipulate plane and solid figures, from the simplest to the most complex.

Freely manipulate figures at any stage to test the construction, make conjectures, measure or remove objects, calculate, make changes, or start all over again

Cabri II Plus is cutting-edge tool for teaching and learning geometry, designed for teachers as well as for students at all levels, from elementary school to university. Software recognized by experts in pedagogy, specifically for its simplicity of use and solid educational foundation.

CREATING YOUR FIRST CABRI 3D DOCUMENT

Double-click on the Cabri 3D v2 icon. The program will automatically create a single-page document containing a work area that is a white area with a gray base plane in the center.

YOUR FIRST 3D CONSTRUCTION First you will construct two three-dimensional objects. This will illustrate a number of Cabri 3D functions.

Constructing a sphere A toolbar at the top of the Cabri 3D document window provides a series of toolboxes. Click and hold the Surfaces toolbox (4th button from the left) and choose Sphere from the dropdown menu.

The mouse pointer changes into a pencil. Click once about 1 cm to the left of the base plane’s center point, then click again about 2 cm to the left of the fi rst point.

To modify the sphere, click on the Manipulation. To change the size of the sphere, use the mouse to click and drag To modify the sphere, click on the Manipulation.

To change the size of the sphere, use the mouse to click and drag either the first or second point that you constructed. To move the sphere, select it and drag it to a new position using the mouse.

You have constructed a sphere!
