Problem:
A polygon with $6$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.327 & 0.089 \\
 -0.216 & 0.874 \\
 0. & 0. \\
 0.163 & 0.783 \\
 0.236 & 0.736 \\
 0.301 & 0.68 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Angles: $\{1.7,1.72,1.86,3.01,2.8,1.47\}$ 
Type: Convex 
Perimeter: $2.44$ 
Area: $0.35$
