How many triangles are present in the given figure?

22

The logic followed here is;

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

1+2= 03  (TLV) 

1+2= 03  (TOV)

1+2= 03  (URW) 

1+2= 03  (UMW)

And, the other triangles are;

NOT, POV, QRU, WRS, NOL, POL, QRM, SRM, NLP, QMS

Therefore, there are 03+03+03+03+10= 22 triangles in the above figure.
