What Do You Know About Hinged Dissections?
In geometry, hinged dissections are a type of dissection problems that possess one chain-like property, which makes all of their respective pieces connected into a chain by certain points. Thus, the improvement starting with one figure then onto the next can be completed by swinging the chain ceaselessly, without separating any of the associations. Hinged dissections are also regarded to as Dudeney dissections or swing-hinged dissections.
