Rectangle to Square (Posted on 2013-08-13) Difficulty: 2 of 5

A rectangle ABCD is to be cut into three pieces
(with two straight line cuts) and the pieces re-
arranged into a square.

Define the endpoints of the cuts.

Note 1: |AB|/4 ≤ |BC| < |AB|.

Note 2: A straight line cut (as the name implies)
            is a cut along a straight line that
            divides a piece into two pieces.
