Jack veut faire tondre son jardin par sa chèvre. Son jardin est un carré de 5m de coté. Malheureusement, il ne peut pas mettre de barrière autour de son jardin et si sa chèvre sort du jardin, son voisin sera furieux et tuera la chèvre. Il cherche donc un moyen d'attacher la chèvre pour qu'elle tonde tout son jardin sans en sortir.
|
||||
\begin{enumerate}
|
||||
\item S'il met un piquet au milieu de son jardin et qu'il y attache la chèvre, est-ce qu'elle tondra tout le jardin sans en sortir?
|
||||
\item Trouver une façon d'attacher la chèvre.

Calculer la distance de $A$ à la droite $(BC)$ revient à calculer la distance $AC$ car le triangle $ABC$ est rectangle en $C$.

\parbox{1.5cm}{\dotfill} est un triangle rectangle en \parbox{1cm}{\dotfill} donc d'après le théorème de \parbox{3cm}{\dotfill} on a

\parbox{1cm}{\dotfill} & = & \parbox{1cm}{\dotfill} \\[0.5cm]
