Hexagon transformations
Can you cut a regular hexagon into two pieces to make a parallelogram? Try cutting it into three pieces to make a rhombus!
Problem
Shown below is a regular hexagon.

How could it be cut into two pieces which, when put together, make a parallelogram?
How could it be cut into three pieces which, when put together, make a rhombus?
How could it be cut into four pieces which, when put together, make two equilateral triangles?
You could print and cut out hexagons from the sheet of hexagons.
