How many triangles are there in the given figure?

17

The logic followed here is;

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

1+2= 03  (BNP) 

1+2= 03  (BLM)

1+2= 03  (BAD)

1+2= 03  (DEF)

And, the other triangles are;

AOC, COD, ABC, BDC, ACD

Therefore, there are 03+03+03+03+05= 17 triangles in the above figure.
