Review for "Pantographe 1"

Symétrie axiale

Global comment:

Review filed on 2011/10/27 17:38 by Christian Mercat.

On bouge le point bleu et la trace de ce point et du point symétrique se dessinent. La symétrie axiale est claire. La démontrer n'est pas si facile. Ceci est un modèle virtuel avant réalisation effective en "mécano".
This review is done without a trial in classroom.
