Given that Hannah has 11 toothpicks that are the same length
When she uses only one toothpick for each side then we see that all sides would be equal whether quadrilateral or triangle.
Hence she can make equilateral triangles, rhombuses or squares out of these 11 toothpicks
Either one equilateral triangle, and 2 rhombuses, or one equil. triangle and 2 squares or 1 equil triangle with 1 square, 1 rhombus or 2 equil triangles with one square or rhombus
