How many triangles are present in the following figure?

22 16 18 20

20

THE LOGIC; The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03  (ABC)  1+2= 03  (DCB) 1+2= 03  (AEG) 1+2= 03  (DHF) 1+2= 03  (CEH) 1+2= 03  (BGF)   And, the other triangles are; ABD & ACD. Thus, total 20 triangles.
