How many triangles are present in the following figure ?

The logic followed here is;

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

1+2= 03  (BMN) 

1+2= 03  (LCO)

And, the other triangles are;

ALM, DON, PQR, SQR, PMQ, NQS, ORS, LPR, ACB, DCB

Therefore, there are 03+03+10= 16 triangles in the above figure.
