\begin{enumerate}
|
||||
\item Tracer les agrandissements ou les réductions des triangles suivants pour que les hypothénuses mesurent:
|
||||
\begin{center}
|
||||
5cm \qquad 8cm \qquad 12cm \qquad 15cm
|
||||
\end{center}
|
||||
|
||||
\includegraphics[scale=0.7]{./fig/triangle_repro}
|
||||
|
||||
\item Mesurer la longueur du côté adjacents pour compléter le tableau.
|
||||
|
||||
\hspace{-1cm}
|
||||
\begin{tabular}{|*{6}{p{2.5cm}|}}
|
||||
\hline
|
||||
Hypothénuse & 5 & 8 & 10 & 12 & 15 \\
|

\hline
|
||||
Adjacent angle = .... & & & & & \\
|
||||
\hline
|
||||
\end{tabular}
|
||||
|
||||
\item Ce tableau est-il un tableau de proportionnalité?
|
||||
|
||||
\item Comment peut-on calculer la longueur du côté adjacent quand l'hypothénuse mesure 10cm?
