Hint 3 of 3
Four of the five turn up easily — the answer is the single shape you cannot find.
Show solution
Approach: search the tiling for each named polygon
- Look through the big tiled picture and tick off each shape you can find.
- Triangles, squares, hexagons and octagons all appear among the tiles.
- No 12-sided dodecagon appears, so the missing figure is the dodecagon (D).
