Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.086 & 0.727 \\
 0.466 & 0.496 \\
 0.537 & 0.183 \\
 0.545 & 0.65 \\
 0.823 & 0.562 \\
 0.886 & 0.17 \\
 0.906 & 0.262 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $2.28$ 
Type: Simple 
Angles: $\{0.38,3.95,1.83,1.74,2.66,2.15,3.\}$ 
Area: $0.2$
