Contents

The following pages are some of the areas that can be explored using the hyperbolic geometry menu. Each has a CabriJava figure embedded in the page. The control bar of the CabriJava figure can be used to show a step by step construction of the figure. The figure can be animated or a trace set up and all the Cabri figures can be downloaded using the rightmost icon on the control bar.
