Abstract
Can you decompose a regular triangle into four pieces and reassemble them to form a square? H. Dudeney performed the trick with a brass-hinged mahogany model before the Royal Society of London in 1905. We are to guide the participants through the construction with Geometer's Sketchpad on this famous dissection problem. For the preparation we invite the participants to concentrate on this figure deeply:
Computing environment required: Windows with the software Geometer's Sketchpad installed.
Limitation on the number of the audience: the same number as available PC's.
A wireless mircrophone-speaker is appreciated.
