Find the number of triangles 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  (ALM) 

1+2= 03  (ACB)

1+2= 03  (DCB)

And, the other triangles are;

RSL, VUM, RNC, VPB, COW, QOB, WOD, OQD, ABD, ACD

Therefore, there are 03+03+03+10= 19 triangles in the above figure.
