Problem:
A polygon with $8$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.529 & 0.636 \\
 -0.523 & 0.689 \\
 -0.518 & 0.096 \\
 -0.185 & 0.028 \\
 0. & 0. \\
 0.064 & 0.088 \\
 0.313 & 0.855 \\
 0.315 & 0.543 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Area: $0.54$ 
Type: Convex 
Perimeter: $2.91$ 
Angles: $\{3.,1.79,3.09,2.05,3.02,2.63,1.38,1.89\}$
