Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.008 & 0.171 \\
 0.356 & 0.309 \\
 0.379 & 0.349 \\
 0.429 & 0.043 \\
 0.497 & 0.435 \\
 0.675 & 0.699 \\
 0.787 & 0.355 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Area: $0.18$ 
Type: Simple 
Perimeter: $2.16$ 
Angles: $\{0.67,2.13,1.98,0.91,3.49,2.74,3.8\}$
