The optimal solution to the problem of dividing an equilateral triangle into the minimal number of pieces and recombining them into a square, known as "Dudeney's Puzzle," has been proven after 120 ...

Over 120 years ago, Henry Ernest Dudeney posed the famous dissection problem of transforming a triangle into a square by cutting it into as few pieces as possible. In a new study, researchers have ...

In 1907, the English author and mathematician Henry Ernest Dudeney posed a puzzle: Can any equilateral triangle be cut into ...

A geometry problem over a century old has just found its definitive answer. Mathematicians have confirmed that the solution proposed by Henry Dudeney in 1907 was indeed the most efficient possible.

Dudeney’s original solution for transforming an equilateral triangle into a perfect square through dissection involves only four pieces, a solution that has now been proved to be the optimal solution.
