Al laboratori matem\u00e0tic d’avui hem aplicat el teorema de Tales per poder mesurar l’al\u00e7ada de coses inaccessibles per nosaltres com per exemple l’al\u00e7ada del edifici del institut, dels arbres del pati, de les faroles, de la cistella de b\u00e0squet,…<\/p>\n

Per aix\u00f2 ho vam fer a partir de les mesures de les seves ombres (sort que feia sol!) i tenint en compte que la proporci\u00f3 que hi ha entre l’al\u00e7ada de l’edifici i la seva ombra, \u00e9s la mateixa que la proporci\u00f3 que hi ha entre l’al\u00e7ada d’un de nosaltres i la nostra ombra si ho mesurem al mateix moment.<\/p>\n

\"Resultat(Pel Teorema de Tales es compleix que A \u00e9s a B com D \u00e9s a C)<\/em><\/p>\n

Per tant primer ens vam mesurar nosaltres i les nostres ombres:<\/p>\n

Despr\u00e9s vam mesurar l’ombra del que vol\u00edem calcular l’al\u00e7ada:<\/p>\n

I despr\u00e9s vam aplicar Tales per poder trobar l’al\u00e7ada desconeguda.<\/p>\n

I pensar que aix\u00f2 ho va descobrir Tales per mesurar les pir\u00e0mides d’Egipte al S.VI a.C.! que llest que devia ser!<\/strong><\/p>\n
