Problem:
A polygon with $7$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.078 & 0.01 \\
 0.08 & 0.633 \\
 0.167 & 0.299 \\
 0.323 & 0.727 \\
 0.659 & 0.678 \\
 0.67 & 0.251 \\
 0.739 & 0.127 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Perimeter: $2.49$ 
Area: $0.35$ 
Type: Simple 
Angles: $\{1.1,1.24,3.62,1.74,2.63,1.68,3.7\}$
