Interactive Geometry

The following Java applets were generated using C.a.R.; some of them are equvalent to the exercises in Euclidea — a cool collection of interactive geometric puzzles.

Since in all major browsers the support for Java plugins has ended, we recommend to install Java Developers Kit (JDK) and open the exercises using the command appletviewer url.... for example, to open the first exercise you use the following command:

appletviewer http://anton-petrunin.github.io/birkhoff/car/Angle%20bisector.html

On windows, before executing the command, you may need to navigate to the folder with appletviewer, it should be something like C:\Program Files\Java\jdk1.8.0\bin
