Correct Answer: B
Solution :
[b] The figure may be labelled as shown: The simplest triangles are: AOQ, DIJ, EPK, EKO, PLB, LBI, JCN, CNR, RFM, FMQ, IGH, HJG i.e. 12 in number. The triangles composed of two triangles such as: EOP, PBI, FQR, RJC, IGJ, EIG and FGJ. i.e. 7 in number. The largest triangles are ABC and DEF i.e. 2 in number. Thus, there are 12 + 7 + 2 = 21 triangles in the given figure.You need to login to perform this action.
