How many triangles are there in the given figure?

17

The logic followed here is;

(let's keep in mind the base, means how many triangles are there in the base)

1+2= 03  (ANM) 

1+2= 03  (ACM)

And, the other triangles are;

ANB, BNM, BDM, ALC, CLM, ACM, AMB, CBD, MLB, ALB, CNM

Therefore, there are 03+03+11= 17 triangles in the above figure.
