【Solution】Solution: $(10+9+6+6+6+5+3+3+2+1)+(9+7+5+6+5+4+2+2+1)+(6+6+6+5+3+3+2+1)$
$$
\begin{array}{l}
+(6+6+5+3+3+2+1)+(6+5+4+2+2+1)+(5+4+2+2+1)+(2+2+2+1)+(2+2+1)+(2+1) \\
+1 \\
=51+41+32+26+20+14+7+5+3+1 \\
=200 \text { (triangles) }
\end{array}
$$

Answer: The number of triangles that can be formed with the 12 points in the figure as vertices is 200.
The answer is: 200.
