"OMOTETIE e SIMILITUDINI"
OMOTETIE e SIMILITUDINI
Ovvero come ingrandire o ridurre una figura, conservandone la forma e i rapporti
tra i suoi elementi.
E aiuta a risolvere questo tipo di problemi:
Come si fa a quadruplicare o ridurre ad un quarto questo rettangolo?
Vedremo come:
- COSTRUIRE una omotetia, una similitudine e poligoni simili.
- RICONOSCERE gli invarianti geometrici di una omotetia.
- CONOSCERE i teoremi di Talete, Euclide e loro applicazioni.
- APPLICARE le descrizioni analitiche di una simmetria, una traslazione, una isometria, una omotetia, una similitudine.
