How many triangles are there in the given figure?

13 12 11 10

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  (ACT)  1+2= 03  (BLM) 1+2= 03  (BNO) And, the other triangles are; ARS & PUQ Therefore, there are 03+03+03+02= 11 triangles in the above figure
