How many triangles are there in the given figure?

13 12 14 15

13

The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03  (BLM)  1+2= 03  (BAD) 1+2= 03  (DPN) 1+2= 03  (DEF) And, the other triangles are; AED Therefore, there are 03+03+03+03+01= 13 triangles in the above figure.
