Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.244 & 0.306 \\
 0.415 & 0.724 \\
 0.521 & 0.026 \\
 0.583 & 0.033 \\
 0.88 & 0.826 \\
 0.899 & 0.199 \\
 0.93 & 0.601 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Simple 
Perimeter: $2.37$ 
Area: $0.39$ 
Angles: $\{1.97,2.23,2.78,2.13,2.85,1.57,2.18\}$
