Example labels such as proof24, etc., mean Proof #24 from the 72 proofs in the webpage:

Except for proof01, proof24, and very few others, all other solutions do not have the corresponding animated versions as we do. Some examples have dynamic versions meaning that some points in the diagrams can be dragged. This collection includes about a dozen of proofs in the three excellent books on PWW. However, we currenlty do not include those proofs that involve algebraic computations in the three books. The rest proofs are from other books.

The original credit explanation of each proof will be inserted into each example soon. Of course any errors or misrepresentations are our faults.
