Problem:
A polygon with $6$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.322 & 0.779 \\
 0.469 & 0.591 \\
 0.58 & 0.779 \\
 0.586 & 0.687 \\
 0.716 & 0.867 \\
 0.879 & 0.804 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $1.36$ 
Type: Simple 
Angles: $\{1.13,1.55,2.19,4.69,0.46,2.55\}$ 
Area: $0.05$
