  That image just demonstrates what was mentioned in the article, that the sphere cannot be covered only with regular hexagons, but a part of them must be replaced with regular pentagons, so the angles that are multiples of 30 degrees are not sufficient. So the previous poster was right.

  An angle projected on a plane is not the same as a 3D angle. Also see the structure of diamond (109 degs).
