Students use constructions to explore geometric shapes and properties. Students can study and make conjectures about geometric shapes without having to draw them. The software includes a full complement of transformations including translation, rotation, reflection and inversions. A function feature allows the user to define any set of constructions that may then be executed on a given shape. Libraries of functions can be developed and saved.
A teacher's manual includes a tutorial, a description of each menu, teaching suggestions and some suggested units. Inductive and deductive thinking patterns can be employed.

Geometry: An Integrated Approach. (Print-Non-Fiction). Larson, Roland E., Laurie Boswell and Lee Stiff. D. C. Heath and Company (HTH), 1995. ISBN 0-669-31665-2 ($58.50 hdc).
This text follows National Council of Teachers of Mathematics standards. Using a discovery approach, it includes suggestions for cooperative learning, experiments and use of technology. The book presents proof as a way of developing deductive reasoning skills. Students are encouraged to put logical reasoning to use in geometric proof and in the interpretation of data. One technology activity per chapter gives students practice with computer drawing programs, graphing calculators and spreadsheets. Frequent hands-on use of models helps students visualize concepts.

Geometry: An Introduction. (Video). (Math Sense Series). ACCESS Network (MHP), 1990. 28 min. Dup. order no. V8120.
As a basis for developing geometric concepts, this program explores the use of terms, postulates, axioms and theorems. The program then shows how our knowledge of is expanded by applying logic to these known geometric definitions. The program examines the use of the congruence postulates for triangles and develops a proof for the isosceles triangle theorem.

Geometry: Chords in Circles. (Video). (Math Sense Series). ACCESS Network (MHP), 1990. 25 min. Dup. order no. V8122.
The chord theorem, the right bisector of a chord passes through the centre of a circle is examined in depth in this program. Equations, proofs and problems related to chords are the principle areas of study.

Geometry: Tangents to Circles. (Video). (Math Sense Series). ACCESS Network (MHP), 1990. 26 min. Dup. order no. V8123.
This program examines the properties of tangents to circles. The theorem "any tangent drawn to a circle os perpendicular to a radius drawn to its centre" os proved and then applied to a variety of problems.
