Note: If the shape doesn't fit on the screen then you can drag and zoom:
*

**Shift+Click**to drag the shape around. ***Right Click**to get a menu which includes the 'Zoom' option. Right clicking on a slider will let you animate it.See what happens when you:
* Change the side lengths
* Add or remove side lengths (what shapes can you get with only 2 side lengths? Only 3?)
* Alter the angle (60, 75, 90 and 120 degrees are interesting to explore)
When a shape doesn't 'join up', is it just because the applet hasn't drawn enough sides, or will it *never* join up no matter how many more sides are drawn?
