Cabri 3D 

Combines fundamental geometric objects and constructs 2D and 3D figures. The geometric objects can be segments, points, angles, solids, and transformations. It uses fundamental algebraic concepts to create expressions such as variables and operations.

Until now three-dimensional geometry was difficult to teach – the complexity of designs in perspective, models that are difficult and time-consuming to construct… Cabri 3D is the only program that enables you to alleviate these construction difficulties and that also contains the benefits of interactive geometry.

Construct 2-D and 3-D figures, from the simplest to the most complex, by combining fundamental geometric objects such as points, angles, segments, circles, planes, solids and transformations.

Create expressions using fundamental algebraic concepts, such as numbers, variables and operations.

Connect geometry and algebra by measuring length, angles, area and volume and then attaching these numeric values directly to the figure to use them in calculations or in algebraic expressions.

Explore a figure's properties by manipulating its variable elements.

Observe the effects of dynamic transformations like shrinking and enlarging.
