The logic followed here is;
(let's keep in mind the base, means how many triangles are there in the base)
1+2= 03 (ACE)
1+2= 03 (MCE)
1+2= 03 (BDF)
1+2= 03 (LDF)
And, the other triangles are;
ACM, AEM, LDB, FEB, CMO, EMN, OLD, NLF, CNO, OEC, OFD, DNO, CEN, OEN, OFN, DNF, EOF CND
Therefore, there are 03+03+03+03+18= 30 triangles in the above figure. |
