What could you say about the angles of two congruent triangles ?\pause

Is the converse true ? Give an exemple or a counter-example ?

Three ways to do it.

\end{frame}



\begin{frame}{How to prove congruent triangles ?}

The SSS way : Using the definition.\\
Prove that the triangles have three pairs of equal sides.
\begin{center}
\psset{unit=0.75cm} \pspicture(0,-0.5)(9,2.5)
\pspolygon(0,0)(4,0)(3,2)
\psline(1.9,0.1)(2.1,-0.1)
\pscircle(1.5,1){0.1}
\psline(3.35,1.05)(3.55,1.15)
\psline(3.4,0.95)(3.6,1.05)
\pspolygon(5,0)(9,0)(8,2)
\psline(6.9,0.1)(7.1,-0.1)
\pscircle(6.5,1){0.1}
\psline(8.35,1.05)(8.55,1.15)
\psline(8.4,0.95)(8.6,1.05)
\endpspicture
\end{center}
\end{frame}

\begin{frame}{How to prove congruent triangles ?}

The SAS way.\\
Prove that the triangles have two pairs of equal sides and the angles between these sides equal. 

\begin{center}
\psset{unit=0.75cm} \pspicture(0,-0.5)(9,2.5)
\pspolygon(0,0)(4,0)(3,2)
\psline(1.9,0.1)(2.1,-0.1)
\pscircle(1.5,1){0.1}
\psarc(0,0){0.5}{0}{32}
\pspolygon(5,0)(9,0)(8,2)
\psline(6.9,0.1)(7.1,-0.1)
\pscircle(6.5,1){0.1}
\psarc(5,0){0.5}{0}{32}
\endpspicture
\end{center}
