Application of cabri 3d in teaching stereometry

Cabri 3D is a software which connects geometry and algebra to enable measuring length, distance, area, angles, scalar product, volume and use them in calculations or in algebraic expressions. Cabri 3D gives new opportunities for teaching three-dimentional Euclidean geometry. In this work we describe some tools and functions of Cabri 3D. We also give a skech of using this mathematical software to create 2D and 3D figures and explore a figure’s properties by manipulating its variable elements.
