Entre l&#8217;alumnat de 1r i 2n d&#8217;ESO hem constru\u00eft aquest magn\u00edfic arbre de Nadal matem\u00e0tic. Es tracta de l&#8217;espiral de Theodor, constru\u00efda amb 203 triangles rectangles de diferents tamanys. Per a construir-los, els alumnes s&#8217;han basat en el teorema de Pit\u00e0gores i han constru\u00eft triangles amb un catet de mida 1 l&#8217;altre de mida \u221a1, \u221a2, \u221a3, \u221a4 i aix\u00ed successivament, fins arribar a \u221a203. A continuaci\u00f3, hem enganxat tots els triangles de manera ordenada un al costat de l&#8217;altre, de manera que han format una espiral en 2D que hem convertit en 3D per tal d&#8217;obtenir aquest espectacular arbre de Nadal matem\u00e0tic. Gr\u00e0cies a tot l&#8217;alumnat que ha col\u00b7laborat a fer-ho possible! I al departament de matem\u00e0tiques que ho ha dinamitzat tot. Podreu admirar aquest arbre a la biblioteca del centre.<\/p>\n\r\n\t<div class=\"slideshow_container slideshow_container_style-light\" style=\" \" data-slideshow-id=\"16842\"
