How many triangles are there in the given figure?

10 12 11 13

11

The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03  (AFO)  1+2= 03  (IFG) 1+2= 03  (POG)  And, the other triangles are; ORC & AFG Therefore, there are 03+03+03+02= 11 triangles in the above figure.
