How many triangles are there in the given figure?

13 15 12 14

13

The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03  (PQR)  1+2= 03  (PBR) 1+2= 03  (MNC)   And, the other triangles are; PBQ, RBQ, ALM, ANC Therefore, there are 03+03+03+04= 13 triangles in the above figure.
