Pierre Wantzel

From Wikipedia, the free encyclopedia

Pierre Laurent Wantzel (June 5, 1814 in ParisMay 21, 1848 in Paris) was a French mathematician.

In a paper from 1837[1], Wantzel proved that

  1. doubling the cube
  2. trisecting the angle
  3. constructing a regular polygon whose number of sides is not the product of a power of 2 and any number of distinct Fermat primes (i.e. that does not fulfill the same conditions proven to be sufficient by Carl Friedrich Gauss)

are all impossible using only compass and straightedge.
