How many triangles are there in the figure given below?

12

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  (ANP)

1+2= 03  (ABC)

And, the other triangles are;

STD, BCD, QRD

Therefore, the total number of triangles in the above figure are 03+03+03+0+= 12 triangles..
