This Demonstration shows how to construct a triangle with a given base length c, an altitude h_c from C to the base and the difference ?-? between the angles at A and B. The problem was posed to Josip Plemelj (1873-1967) by his mathematics teacher...

![Dissection of a Square to a Parallelogram with the Same Base
http://demonstrations.wolfram.com/DissectionOfASquareToAParallelogramWithTheSameBase
The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
Two polygons of the same area are said to be equivalent. In [1], Tarski defines the degree of equivalence of two equivalent polygons V and W as the smallest natural number n for which there exists a dissection of V to W using n pieces. The function is d...
