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 ...

So, what's with the biscuits? Oh a triangulator machine! Very cool! Right, there are four different types of triangle. First, here's an isosceles triangle, it has two equal length sides and two ...

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 ...

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?

The three angles in a triangle add up to \(180^\circ\). If two of the angles are known then the third can be calculated by following these steps: Add the two known angles together. Subtract the ...

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 ...

Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of triangle and develop students' reasoning with properties of different classes of triangles to ...

This event signals the start of Spring in the Northern Hemisphere and Autumn in the Southern Hemisphere, a transition that also manifests in our evening skies as winter constellations start to vanish.
