Figure solide con Geogebra IL CUBO

Ragazzi anche oggi c’è qualcosa che voglio mostrarvi, conoscerete già GEOGEBRA, il programma di matematica dinamica…

Ricordate,;.
Se no avete GEOGEBRA scaricatelo qui:

Conoscerete tutti i le figure solide.?!
Oggi impareremo a fare la più semplice tra queste…

Partiamo quindi dal cubo:

  • selezioniamo, nella barra degli strumenti in alto, lo strumento “poligono regolare”, fissiamo due punti possibilmente non paralleli ad uno dei due assi…, e diciamogli n° vertici “4”
  • abbiamo ora il quadrato di partenza…
    selezioniamo lo strumento “segmento di lunghezza fissa” e ponendo un punto fuori dal quadrato, diciamogli lunghezza “AB” (lato del quadrato)… allineiamo ora questo segmento con l’ asse delleordinate (Y)
  • selezioniamo lo strumento “vettore-tra due punti” ed andiamo adunire gli estremi del segmento creato al passo prima
  • selezioniamo ora lo strumento “traslazione”e selezioniamo i 4 vertici del nostro quadrato (uno alla volta), e poi selezionare il vettore creato precedentemente, per traslarli
  • abbiamo ora tutti gli “8” i vertici del nostro cubo…
    selezioniamo lo strumento “poligono” e uniamo tutti i vertici di ogni faccia…

 

Il risultato finale risulterà pressocchè così…

Ecco a voi il vostro cubo finito
