#PuzzleOfTheDay: See four equilateral #Triangles in the diagram below.

If #Length of AB is 11 cm, what is the length of the yellow line?

Hostile Triangles.

My thoughts as I spotted the staircase and started to frame the shot:

1. Hey, cool geometry! 😀
2. I wonder what those pyramids are for? 🤔
3. Oh. They're anti-homeless design, aren't they.😩

Geometry creating a world of corners, triangles, lines and shapes. The light comes through different angles and the patters might appear surprising.

This pictures are taken in the mail train station in Vienna. It (re)opened 11 years ago and is my entry to the city several days a week.

Camera: Panasonic Lumix TZ101
Edit: none, sooc

Geometry question:

I have a light (in parallel beams) shine on an object and the object casts a shadow on a plane that is at 90° to the direction of light.
When I now angle the plane to 45° degrees, the area of the shadow is spread out over a larger area of the plane by a factor of √2.

But if I angle the plane 45° on one axis, and also 45° on a second axis, is the shadow now stretched out by a factor of √2 times √2?

Finally finished* a post I started a month ago on a program I wrote a month before that. A rehash of a project I would tinker on in college.

We're drawing images using a fixed number of triangles and genetic algorithms. Includes instructions on how you can download the program and make your own art from your own images.

You should do it, they would look great at your funeral.

🤔 Ah, the mystical world of 16-byte #x86 #assembly, where #coding #wizards conjure #Sierpinski #triangles from the ether and somehow turn them into music. 🎶 Because we all know what the world really needs is yet another way to remind us that coding is a #strange #cult where people speak in tongues of "int 10h" and worship at the altar of "mov ds, bx." 🙄

I've assembled and stuffed 9 of the 12 pyramids now, still 3 to go...

Somehow it's taken me all day to add the edges to the triangles. Now to actually sew them together.

#26 Recursive Grid.

After playing around with recursive shapes I chose the triangle. One black, one transparent building a rectangle together.
Not as awesome as most of the other creations for this prompt but I call it done.

I really like recursive patterns, fractals and other algorithms resulting in unexpected art.

@sam_hartburn That's very pretty! Your mention of triangles and music reminded me of a diagram system I saw a short while ago: https://en.wikipedia.org/wiki/Tonnetz - and TIL by reading the wikipedia article that it was first described by Euler.

There's an interactive webapp: https://girlinbluemusic.com/interactive-tonnetz/
and several YT videos - this one being the one which introduced me to the concept in the first place: https://www.youtube.com/watch?v=NQ7LkWCzKxI

In a riveting saga of academia's elite 🤓, a consortium of scholars has pooled their intellectual prowess to reinvent the wheel – this time with triangles! 🔺 #Arxiv promises code "soon," but we all know that means as soon as the #researchers can remember their #GitHub passwords. 🤔
