You may hear students say words like ‘paralyzed’ triangle for isosceles and equilateral triangles after noticing the restrictive movements of these triangles upon dragging. Properties of symmetry: - ...

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 ...

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.

Late on Thursday night and into the early hours of Friday, the full moon turned a beautiful reddish color as it drifted ...
