How many triangles are there in the given figure?

8 11 12 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  (LBN) And, the other triangles are; ALM, CNM, LQP, MQR, PNR, PQR, LMN, ABC Therefore, the number of triangles are 03+08= 11 triangles
