How many triangles are there in the following figure?

30

The logic followed here is;

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

1+2= 03  (AOC) 

1+2= 03  (EOG)

1+2= 03  (CDH) 

1+2= 03  (CGH)

1+2= 03  (FUV)

1+2= 03 (FGV)

And, the other triangles are;

AOE, COG, AEC, ECG, ACG, EAG, CGD, HGD, UFG, UVG, BUD

Therefore, there are 03+03+03+03+03+03+11= 30 triangles in the above figure.
