Problem:
A polygon with $3$ vertices has the coordinates $\left(
\begin{array}{cc}
 0.459 & 0.92 \\
 0.778 & 0.352 \\
 0.86 & 0.148 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Angles: $\{0.03,0.1,3.01\}$ 
Area: $0.01$ 
Perimeter: $1.74$ 
Type: Simple
