Two polygons and are equivalent () if they have the same area. In the article "On the Degree of Equivalence of Polygons", Tarski defines the degree of equivalence of two equivalent polygons and as the least integer for which there exists an -piece dissection of to .

The method used in the proof of the theorem that two polygons equivalent to a third are equivalent to each other is called the double subdivision-network.
