How many triangles are there in the given figure ?

The logic followed here is;

(let's keep in mind the base, means how many triangles are there in the base)

1+2+3+4= 10  (ABC)

1+2+3+4= 10  (ADE)

And, the other triangles are;

FAD & GAE

Therefore, the total number of triangles in the above figure are 10+10+02= 22 triangles.
