Hint 2 of 2
Neighbouring hexagon centres form little triangles, giving a triangular grid.
Show solution
Approach: join centres to form a triangular lattice
- Put a point in the middle of each hexagon.
- Joining the centres of two hexagons that share an edge gives short segments.
- Because the hexagons sit in a triangular cluster, these segments build a triangular grid.
- That pattern is picture C.
