How many triangles are present in the given 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  (MSD) 

1+2= 03  (LRB)

And, the other triangles are;

LRP, BRQ, PSM, QSD, PRQ, PSQ, LPB, QPB, LBQ, LPQ, PQD, PMD, PMQ, MDQ, BPD, LQM

Therefore, there are 03+03+16= 22 triangles in the above figure.
