How many triangles are there in the given figure?

23 20 22 24

22

The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03  (ALM) 1+2= 03  (ABC) 1+2= 03  (FQR) 1+2= 03  (FDE) 1+2= 03  (UNP) 1+2= 03  (UDE) And, the other triangles are; BDU, CEU, FDU, FEU Therefore, the number of triangles are 03+03+03+03+03+03+04= 22 triangles
