Cabri Geometry II Plus

Cabri Geometry provides an interactive computer environment for your students to do and learn geometry (Euclidean, transformational and analytical).

Some educational features include:

construction of points, lines, triangles, polygons, circles, and other basic geometric objects;
enables testing of hypotheses about geometric properties (based on Euclid’s postulates);
translation, dilation, and rotation of geometric objects around geometric centres or specified points, plus reflection, symmetry, and inverse;
cartesian and polar coordinates;
easily constructed conics, including ellipses and hyperbolae;
displays the equations of geometric objects;
continuously computed locus;
exploration of advanced concepts in projective and hyperbolic geometry;
animation illustrates dynamic characteristics of figures;
figure annotation and measurement.

Cabri is flexible and easy to use for teacher demonstration and by students.
