Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.039 & 0.203 \\
 0.089 & 0.233 \\
 0.145 & 0.019 \\
 0.215 & 0.037 \\
 0.323 & 0.339 \\
 0.403 & 0.256 \\
 0.667 & 0.035 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Simple 
Angles: $\{0.29,2.06,0.76,0.08,5.4,1.07,6.04\}$ 
Area: $0.1$ 
Perimeter: $2.1$
