Problem:
A polygon with $3$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.05 & 0.601 \\
 0.227 & 0.651 \\
 0.977 & 0.371 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Simple 
Area: $0.04$ 
Angles: $\{0.52,0.11,2.51\}$ 
Perimeter: $1.94$
