Note: If the shape doesn't fit on the screen then you can drag and zoom: [br]* [b]Shift+Click[/b] to drag the shape around.[br]* [b]Right Click[/b] to get a menu which includes the 'Zoom' option.[br]Right clicking on a slider will let you animate it.

See what happens when you:[br]* Change the side lengths[br]* Add or remove side lengths (what shapes can you get with only 2 side lengths? Only 3?)[br]* Alter the angle (60, 75, 90 and 120 degrees are interesting to explore)[br][br]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?
