Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 -0.733 & 0.915 \\
 -0.726 & 0.704 \\
 -0.279 & 0.879 \\
 -0.028 & 0.734 \\
 0. & 0. \\
 0.163 & 0.452 \\
 0.174 & 0.592 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Convex 
Area: $0.44$ 
Perimeter: $2.84$ 
Angles: $\{1.46,2.37,1.15,2.88,2.11,3.05,2.7\}$
