Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.592 & 0.062 \\
 -0.509 & 0.053 \\
 -0.347 & 0.442 \\
 -0.141 & 0.011 \\
 -0.048 & 0.524 \\
 0. & 0. \\
 0.063 & 0.119 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Convex 
Perimeter: $1.91$ 
Area: $0.22$ 
Angles: $\{1.12,3.14,3.1,1.98,2.39,1.57,2.41\}$
