Problem:
A polygon with $3$ vertices has the coordinates $\left(
\begin{array}{cc}
 0. & 0. \\
 0.154 & 0.336 \\
 0.324 & 0.357 \\
\end{array}
\right)$. Estimate the polygon's interior angles (in radians), area, and perimeter. Also, classify the polygon as 'Simple' or 'Convex'.
Answer:
Type: Convex 
Perimeter: $1.02$ 
Angles: $\{0.31,2.13,0.71\}$ 
Area: $0.03$
