Find how many triangles are there in the given figure.

16 20 14 18

18

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
