Introduction

Purpose

C.a.R. is a software to simulate geometric constructions on a computer. The main advantage is that constructions can easily be changed by dragging one of the primary points. During these changes, the constructions is repainted immediately. Moreover, tracks of points can be drawn.

Things you can do with the computer but not with the real thing are

The main user will be a school teacher, or a school class.

  1. C.a.R. can be used to explore geometry by the learner.
  2. It can display assignments to the student and check the solution.
  3. The teacher can use it to demonstrate geometry.

The program also teaches general principle of computer usage, since it sticks to widely spread interface techniques.

Why Java?

This version of C.a.R. is written in Java (© Registered Trade Mark by Sun). Java makes it possible to run the program in a browser, and to publish constructions and assignments in the Internet. It also makes it possible to use different operating systems.
