How many triangles are there in the given figure?

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  (BKJ) 

1+2= 03  (MNJ)

1+2= 03  (JLD)

1+2= 03  (OPD)

And, the other triangles are;

QCR

Therefore, the total number of triangles in the above figure are 03+03+03+03+01= 13 triangles.
