Which of these triangular jigsaws are impossible to finish?
If the yellow equilateral triangle is taken as the unit for area,
what size is the hole ?
Using the interactivity, can you make a regular hexagon from yellow
triangles the same size as a regular hexagon made from green
Can you find a general rule for finding the areas of equilateral triangles drawn on an isometric grid?
Nick Lord says "This problem encapsulates for me the best features
of the NRICH collection."
Using LOGO, can you construct elegant procedures that will draw
this family of 'floor coverings'?
Recreating the designs in this challenge requires you to break a
problem down into manageable chunks and use the relationships
between triangles and hexagons. An exercise in detail and elegance.
