Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.063 & 0.232 \\
 0.169 & 0.862 \\
 0.215 & 0.86 \\
 0.28 & 0.409 \\
 0.54 & 0.817 \\
 0.546 & 0.93 \\
 0.79 & 0.262 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $2.55$ 
Angles: $\{0.72,4.1,0.87,3.62,1.3,3.39,1.7\}$ 
Area: $0.28$ 
Type: Simple
