|Why is trisecting an angle with a straightedge and compass impossible? Discussion includes several other proofs of impossibility (the largest prime number, the square root of 2, repeating patterns in the plane) and some alternate methods of trisection ("What's With the Ruler and Compass Anyway?"; the Archimedean Spiral; proving it can't be done).|
