@diegorattaggi Happy new year 2024 🎉🥳

Traditionally, my last puzzle of the year. 🥂😍🐅#HappyNewYear2024 #mathiratti

Probability math art with hexagons

Simple, physical example that shows why 2^0 = 1. youtu.be/FD9LJXqYfLQ #MTBoS #ITeachMath #math #maths #mathematics #alg1 #algebra #mathchat

Oh Pascal you rascal!

@andkomi @diegorattaggi @Cshearer41 @le_becachel @HenkReuling All green triangles have the same area and are two-to-two congruent. Because the two angles between hexagon and equilateral triangle are supplementary.

Je viens de retrouver cet exercice, qui a déjà une dizaine d'années 😟. J'aime toujours bien.

What fraction of the total area is shaded?

Two squares and two equilateral triangles. The pink colored area is 4. What's the blue colored area? #GeometryDash #puzzles

The blue and green shaded regions created by these three squares have the same area. What’s the angle?

Lewis Carroll invented one of the fastest algorithms for computing determinants while publishing his most famous novel "Alice in Wonderland" (1865).

What fraction of this regular hexagon is shaded?
