Cabri
3D: Explore the 3rd dimension
Until now threedimensional geometry was difficult to teach – the
complexity of designs in perspective, models that are difficult and
timeconsuming 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.
Cabri: Software serving pedagogy
Tools for
students: «
from exploration to understanding »
With just a few clicks, students can:

Construct 2D and 3D 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.
Make conjectures
about algebraic and geometric properties, and then verify
relationships among various parts of a figure.
Tools for
teachers: «
from lesson plans to assessment »
The teacher can:

Create activities
that:
 facilitate the introduction and understanding of new concepts
 promote the discovery of theorems, instead of just showing
them
 help model reallife situations.

Generate classroom resources
by inserting text or pictures in a figure, modifying graphical
elements, copying/pasting into other software and producing
highquality printouts.

Present activities
to students, have them manipulate figures, observe and guide
them. Using Cabri allows you to better assess individual student
comprehension.

Expand online
by integrating figures that can be manipulated on web pages or
by incorporating Microsoft Office® documents.

Have students solve problems
directly linked to the NCTM standards with possible
interdisciplinary connections to physics, geography and the
arts.
Focus on the features of Cabri 3D adapted especially for middle school
In addition to the features common to all Cabri products, Cabri 3D
includes:
Numeric and geometric tools

Basic constructions
with planes, spheres and lines.

Study of common solids:
with a click of the mouse, the student or teacher can construct
pyramids, parallelograms, cylinders and cones.

Sections of solids:
The user can represent and determine planar sections of convex
polygons.

Unfolding polyhedron into nets:
Cabri 3D unfolds all polyhedron into nets, which are printable
and can be reproduced onto card stock.

Measurements and calculations:
Find measurements related to objects  distances, lengths, area,
volumes and angles, and use them in calculations.
Unique 3D visualization tools

Through tools that facilitate
visualization,
students and teachers can:
 Adjust viewing angles turning around the scene
 Appreciate the rendering of depth of the scene.

Animation
tools: Particularly stimulating for students, the tools enable
them to simultaneously put several elements of a construction in
motion. It is ideal for modeling physical phenomena.

Different
representations and perspectives of the same
figure: the three angles of technical design, various
perspectives.

« Refresh the construction » tool replays the user's
construction.
