  • Can you make a regular hexagon using only blue triangles ?
  • Can you make a regular hexagon using only green triangles ?
  • Can you make a regular hexagon from blue triangles that is the same size as a regular hexagon made from green triangles?
Did that tell you something about blue and green triangles, about how they relate to each other?
  • Can you make an equilateral triangle from blue triangles?
  • Can you make an equilateral triangle from green triangles?
  • Can you make an equilateral triangle from blue triangles that is the same size as an equilateral triangle made from green triangles?
