Problem:
A polygon with $6$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.893 & 0.791 \\
 -0.811 & 0.336 \\
 -0.609 & 0.097 \\
 -0.428 & 0.067 \\
 -0.061 & 0.403 \\
 0. & 0. \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Area: $0.39$ 
Type: Convex 
Perimeter: $2.72$ 
Angles: $\{0.96,2.62,2.44,3.13,1.27,2.16\}$
