Ã€ partir de la figure 1 ci-contre, on veut obtenir la figure 2
puis la figure 3, uniquement Ã  l'aide de la symÃ©trie axiale.

\begin{enumerate}[(a)]
\item Reproduire la figure 1 en prenant $OA=2$~cm et
$OI=1$~cm.
\item Quels sont les axes de symÃ©trie de la figure 2 ?
ComplÃ©ter la figure 1 afin d'obtenir la figure 2.
3. ComplÃ©ter la figure 2 pour obtenir la figure 3.
\item Colorier la figure 3 Ã  l'aide de deux couleurs en
alternant les couleurs.
\item Combien d'axes de symÃ©trie possÃ¨de la figure 3 ? Et la
