Find 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  (BPD)

1+2= 03  (CPD)

1+2= 03  (FCP)

1+2= 03  (BFP)

And, the other triangles are;

FDB, FDC, FBC, DBC, OST, NQR

Therefore, the number of triangles are 03+03+03+03+06= 18 triangles
