Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.13 & 0.56 \\
 -0.048 & 0.133 \\
 0. & 0. \\
 0.107 & 0.702 \\
 0.34 & 0.177 \\
 0.524 & 0.762 \\
 0.68 & 0.671 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $2.44$ 
Type: Convex 
Area: $0.36$ 
Angles: $\{1.92,2.99,1.43,2.65,1.5,2.47,2.74\}$
