How many triangles are present in the following figure ?

15 14 18 16

16

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.
