Lindgren's Dissection of a Parallelogram to a Parallelogram
Lindgren's Dissection of a Parallelogram to a Parallelogram
This Demonstration shows Lindgren's parallelogram-to-parallelogram dissection. Translating a parallelogram along its base we get a P-strip (parallelogram strip). The intersection of P-strips of the given parallelograms is another parallelogram, and it determines the parts of dissection. The parameter is the lengths of the base of the first parallelogram and is the angle between the base and the leg. The parameters and determine the second parallelogram.
