Tangram

Division of a square in the 7 parts of tangram

Operate with the tool: [Polygon-Tools \ Split Polygon _ _ ] producing successively the 7 well known parts.

The game requests a quick construction of various shapes that are formed by rearranging these 7 parts. Usually the contour of the figure under construction is given. The problem is to put the pieces so that the given contour results. In EUC we can hide the division-lines, by coloring them with the same color as the area of the pieces. Thus we can create catalogs of problems and corresponding catalogs of solutions.

Basic problem: rearrange the pieces so that the initial square is produced. You can use a copy of the present file, and after deleting these remarks (text), play, trying to compose various figures. Don't forget that Ctrl+Z udoes the previous move.
