Učenici jednog projektnog tima pripremaju zadatke te ih objavljuju i šalju na rješavanje drugom projektnom timu. Na isti način drug projektni tim rješava postavljene zadatke te priprema zadatke za rješavanje trećem timu. Tako nastaje lanac i li vlakić zadataka. 
    6. Konstantinos T. : Draw a regular pentagon with a side length of 5 cm, reflect it over the point D. Rotate the result by 90 degrees around point D.
          Reflect the total  creation by line BC.

    8. Eudokia K.: Draw a hexagon with side lengths 3cm, vertices A, B, C, D, E, F and the line AC.
        Reflect the hexagon in line AC and rotate the resulting hexagon around vertex B by 45 degrees.

    9.Vasilis T.:Draw a octagon with side length of 5 cm, then perform a central symmetry over point E.
       Then, translate the total shape by vector FB (the diagonal from point F to point B).

  10. Stella S.:Draw a circle with center O and radius length 5cm and a chord AB. Translate the circle by vector OA.
        Then reflect the result by line OB and rotate the final result around point O by 90 degrees.
