The integer dimensions of the parts of the puzzle (2, 3, 5, 8, 13) are successive [[Fibonacci numbers]], which leads to the exact unit area in the ''thin parallelogram''.
Many other geometric [[dissection puzzle]]s are based on a few simple properties of the Fibonacci sequence.<ref>{{cite web |publisher=Math World |last=Weisstein |first=Eric |title=Cassini's Identity |url=http://mathworld.wolfram.com/CassinisIdentity.html}}</ref>
