Mathematicians struggled to find the fewest number of pieces needed to cut an equilateral triangle and rearrange it into a ...

Now, more than 122 years after it was first proposed, Kamata and two other mathematicians have finally proved that a solution ...

TOKYO -- A Japan-U.S. research team on March 10 offered a mathematical proof that "Dudeney's dissection," a challenge to cut ...

Status of changes to the first-generation limit on citizenship Updated The Citizenship Act includes a first-generation limit to citizenship by descent. This limit generally means someone isn't ...

“Over a century later, we have finally solved Dudeney’s puzzle by proving that the equilateral triangle and square have no common dissection with three or fewer polygonal pieces,” says Prof. Uehara.

"We achieved this using a novel proof technique that utilizes matching diagrams." In their study, the researchers proved a key theorem: There is no dissection between an equilateral triangle and a ...

hence proving that a dissection between a square and an equilateral triangle cannot be achieved with three or fewer pieces. The matching diagram played a central role in their proof. In this ...
