How many triangles are present in the given figure?

30

The logic followed here is;

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

1+2= 03  (ACE) 

1+2= 03  (MCE)

1+2= 03  (BDF) 

1+2= 03  (LDF)

And, the other triangles are;

ACM, AEM, LDB, FEB, CMO, EMN, OLD, NLF, CNO, OEC, OFD, DNO, CEN, OEN, OFN, DNF, EOF CND

Therefore, there are 03+03+03+03+18= 30 triangles in the above figure.
