Hmm, an interesting puzzle Pilou! Needs some clever rounding of dimensions to achieve these results. ;-}

For example, I drew the square sides to length 2.24*2 and did not achieve the even 1, 2, 3, 4, 5 sides of the triangles. Then I drew the square with sides 2.238*2, and at least with 1.00 display rounding was able to achieve the same image.
