Problem:
A polygon with $8$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.079 & 0.908 \\
 0.101 & 0.444 \\
 0.108 & 0.637 \\
 0.223 & 0.953 \\
 0.307 & 0.174 \\
 0.353 & 0.271 \\
 0.621 & 0.403 \\
 0.954 & 0.627 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Simple 
Angles: $\{1.77,3.29,2.45,1.09,3.82,3.01,1.01,2.42\}$ 
Area: $0.36$ 
Perimeter: $2.57$
