Problem:
A polygon with $6$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.833 & 0.302 \\
 -0.801 & 0.369 \\
 -0.676 & 0.554 \\
 -0.137 & 0.585 \\
 -0.028 & 0.578 \\
 0. & 0. \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $2.41$ 
Angles: $\{1.47,1.18,1.68,3.02,2.22,2.99\}$ 
Area: $0.32$ 
Type: Convex
