Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.132 & 0.745 \\
 0.184 & 0.152 \\
 0.197 & 0.747 \\
 0.197 & 0.285 \\
 0.302 & 0.313 \\
 0.394 & 0.039 \\
 0.746 & 0.538 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Angles: $\{0.23,3.38,1.96,1.69,1.32,0.97,6.15\}$ 
Area: $0.23$ 
Type: Simple 
Perimeter: $2.95$
