Problem:
A polygon with $9$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.029 & 0.56 \\
 0.169 & 0.032 \\
 0.373 & 0.665 \\
 0.428 & 0.422 \\
 0.738 & 0.097 \\
 0.868 & 0.159 \\
 0.936 & 0.163 \\
 0.964 & 0.679 \\
 0.966 & 0.424 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Angles: $\{1.61,0.84,4.93,1.89,3.54,1.74,3.02,1.55,2.87\}$ 
Perimeter: $3.14$ 
Area: $0.39$ 
Type: Simple
