Find the number of triangles in the given figure.

17 18 16 19

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  (ALM)  1+2= 03  (ABE) And, the other triangles are; SUR, TRV, RSQ, RTQ, CNR, WCR, WDR, DOR, RCD, SRT, CBT, DES Therefore, there are 03+03+12= 18 triangles in the above figure.
