@mathforge.org has done what I’ve never been organised enough to do myself, and catalogued every #geometrypuzzle I’ve ever posted on social media. It looks amazing!

Ahir ens va deixar el Claudi Alsina.
Qui més qui menys coneix la seva tasca com a divulgador i com a professor de didàctica, però jo avui vull reivindicar el seu llegat de llibres de geometria escrits amb el Robert B. Nelsen. Són un tresor. Llegiu-los!

I love breaking the unspoken rule about fraction diagrams (all pieces congruent, not just equal in area). Here are a few of my favourite non-standard representations. A one radian sector fills half the unit square, the curves y = x² and y = √x enclose 1/3 of the square. Can you come up with more?

New career path: Telling everyone that I use generative AI for everything (and then just half-assing it with my own brain) so people I don’t respect throw piles of money at me and are cool with the final product being bad.

Sabies que pots formar un triangle 3:4:5 fent dos plecs en un quadrat de paper?
Només cal fer servir el primer plec per trobar el punt mitjà del costat esquerre i l'altre per dur la cantonada inferior dreta fins allà!

A generalization of the ideas that x.com/tiago_hands & x.com/mathsproofs have been developing lately:
Because of the Law of Sines, if you draw rhombi with side lengths = √circumdiameter in the corners of any triangle, then their areas are equal to the lengths of the opposite sides: A=a, B=b & C=c.

What are the areas of these quadrilaterals?
What are their angles?
x.com/tiago_hands and x.com/mathsproofs are working really hard in these objects, follow them to get updates!!!

It's pretty wild to me that investigators have uncovered that anti-trans campaigns are largely funded by the fossil fuel industry, and that the presumed motivations are pretty directly to redirect the public conversation away from climate change... and that this isn't bigger news.

Happy 3²/4²/5² ! Here's a cool fact about a 3-4-5 right triangle: The circle that fits perfectly in a 3-4-5 right triangle has an area of pi square units! Here's why.
