Latin square or tri-colored “hexagonal” tiling?

Let's take a closer look at the integer points that lie on that circle.

How many different quadrilaterals can you make using four of these points? What are their areas? Which one is the largest?

Solve the following puzzles using four copies of this quadrilateral. You may flip, rotate, and translate the pieces, but it is not allowed to overlap them.

1) Make a square
2) Make a parallelogram
3) Make a trapezoid
4) Make two squares simultaneously
5) Make two golden rectangles simultaneously

Notice that the four vertices seem to lie on a circle.

How can you be completely sure that this is the case?

What are the coordinates of the center of that circle? What's its radius? How do you know?

Which quadrilateras have this property? How can you easily identify them?

The quadrilateral whose vertices are (0,0), (3,0), (2,2) and (0,1).

Let Q be the quadrilateral whose vertices are (0,0), (3,0), (2,2) and (0,1).

What's the length of sides and diagonals of Q?
(the Pythagorean theorem may be useful)

What's the size of the internal angles of Q?
(the ArcTan function may be useful)

What's the area of Q?
(Pick's theorem may be useful)

"Paradoja".

Lo resubo con alt y con censura woke, porque me gustaría mucho que esto saliera adelante.

Hacer promo en Bluesky, tirar una moneda a un estanque. Estreno show (tampoco tengo planeado hacerlo más, en realidad) en La Llama Fest este marzo. Solo para gente con abono. El teatro es muy grande, estoy muy arrepentido de autoprogramarme.

Tumblr post by stimmyabby Sometimes people use "respect" to mean "treating someone like a person" and sometimes they use "respect" to mean "treating someone like an authority" and sometimes people who are used to being treated like an authority say "if you won't respect me I won't respect you" and they mean "if you won't treat me like an authority I won't treat you like a person" and they think they're being fair but they aren't, and it's not okay. 642,270 notes

I think about this post a lot

A modo de resumen:

A famous photograph taken in April 2000 during a federal raid in Miami connected to the custody and immigration case of a six-year-old Cuban boy whose situation had become an international political dispute between the United States and Cuba. The image shows armed federal agents entering a private home to seize the child, who is being held by a relative inside a closet.

This picture was taken in 2000 by an Associated Press photographer who was allowed to be present as an observer. ICE now keeps press blocks away from the areas where they are operating. One of the first actions ICE takes during a raid is to confiscate phones.
