The image shows a circular arrangement of six flower-like shapes with 21st Century Pattern Blocks, leaving an empty, flower-shaped space in the center. Each flower has a hexagon made of one teal kite, two pink triangles, two purple hexagons, and four blue rhombuses, at its center, surrounded by six green triangles and six pink triangles.

El trapecio es un cuadrilátero al que solo le pedimos que tenga 2 lados paralelos.
Como cualquier cuadrilátero, el trapecio tesela el plano.
Ojalá baldosas de trapecios en las calles

Un homme devant un tableau vert devant un addition sigle infini + sigle infini égal ? Il écrit 16 dans le même sens.

Il y a 30 ans à Davos, un poète prend la parole là où l’on parle surtout d’économie. Son message est simple : Internet n’appartient à personne, et surtout pas aux puissants. Une déclaration devenue instantanément un texte majeur.

¿Cómo se construye un rectángulo aúreo?
En un cuadrado de lado 1, toma el punto medio de un lado.
El segmento de ese punto medio al vértice del lado opuesto mide (Pitágoras) (raíz(5))/2.
Si lo trasladamos el segmento resultante mide (1+raíz(5))/2.
El rectángulo formado es aúreo.

Ben Sparks made this wonderful GeoGebra app that lets you create a twisted band (Möbius strip, etc.) and cut it in half or into thirds. As someone who uses GeoGebra quite a bit: Wow! www.geogebra.org/m/v5z33vth
