Problem:
A polygon with $6$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.01 & 0.2 \\
 0.076 & 0.11 \\
 0.098 & 0.861 \\
 0.353 & 0.568 \\
 0.391 & 0.176 \\
 0.72 & 0.609 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Simple 
Area: $0.26$ 
Angles: $\{2.37,2.,2.43,0.81,4.11,0.85\}$ 
Perimeter: $2.4$
