TOKYO -- A Japan-U.S. research team on March 10 offered a mathematical proof that "Dudeney's dissection," a challenge to cut an equilateral triangle and use the parts to create a square with the ...

Statement II: Any two equilateral triangles are similar. (True, because all equilateral triangles have the same angles.) Correct Answer: Option (C) – Both statements are true.

It involved cutting the equilateral triangle into four pieces ... Since the number of possible division patterns appeared infinite, directly checking all configurations was out of the question.

Down in the basement of the bustling Dining and Community Commons (DCC) lies the new geoexchange plant — a little-known facility that plays a crucial role ...

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

In 1907, the English author and mathematician Henry Ernest Dudeney posed a puzzle: Can any equilateral triangle be cut into as few pieces as possible that will fit together to form a perfect square?

When a specific voltage was applied via the STM probe to the distorted triangular structure, it was observed to transform closer to an equilateral triangle. This change indicates that the voltage ...
