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 ...

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 ...

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?

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 ...

Discusses the properties and types of triangles, explaining that a triangle is a closed figure with three sides and angles. It categorizes triangles into equilateral, isosceles, scalene ...
