Proposed by :
Mr. REZGUI SAMI.
At first, would you copy these 9 points on a sheet, and then try to find a method to pass along these 9 points, by using only 4 lines, and without raising the pen from the sheet, good luck !!

Remark : If you hadn't found the solution, and your scientific curiosity push you to know the solution, would you contact me on rezguisami@mailcity.com to give you the password of the solution.
At the time you had the password, you can now reach to the Word file which contains the solution.
Remark : If you have the reading password, you will receive after a second request of the writing password. At this time don't enter anything but rather hit the "Reading only" button, and the document will be open automatically in reading (only !).
