How many triangles are present in the following figure?

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.
