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

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

"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 ...

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

First, here's an isosceles triangle, it has two equal length sides and two equal angles. Oh! Very clever! Now we have an equilateral triangle. Three sides of equal length andall the angles are 60 ...
