\noindent{\bf Naloga}: Napi"site program v Matlabu, ki 
izra"cuna radija in sredi"s"ci o"crtanega in v"crtanega kroga 
trikotniku, podanemu s tremi nekolinearnimi to"ckami v ravnini.
Program naj tudi nari"se sliko trikotnika, obeh krogov in 
sredi"s"c.

Kot podprobleme morate re"siti naslednje:
\begin{enumerate}
  \item Kako poiskati prese"ci"s"ce dveh premic?
  \item Kako dolo"citi ena"cbo simetrale daljice?
  \item Kako dolo"citi simetralo kota?
  \item Kako z ukazom \texttt{plot} narisati kro"znico?
\end{enumerate}

Program preizkusite na primeru trikotnika, podanega z ogli"s"ci
$\bfm{T}_1(1,2)$, $\bfm{T}_2(3,1)$ in $\bfm{T}_3(0,-1)$.
Klic funkcije, ki izri"se spodnjo sliko, naj bo oblike
\texttt{risi\_krog([1 2;3 1;0 -1])}.
