animatie met 12 driehoeken met 90 graden hoeken      De animatie maakt ook gebruik van objectmethodes van de superclass  ¨Vormen¨.

 

bekijk de roterende driehoeken  met de "s'" toets stopt, en met de "r" toets start de rotatie

Met de "1" worden de ruitjes ingeschakeld en met de "2" weer uitgeschakeld
