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= 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
