16
Answer: Option
Explanation:

The figure may be labelled as shown.

The simplest triangles are ABJ, ACJ, BDH, DHF, CIE and GIE i.e. 6 in number.

The triangles composed of two components each are ABC, BDF, CEG, BHJ, JHK, JKI and CJI i.e. 7 in number.

There is only one triangle JHI which is composed of four components.

Thus, there are 6 + 7 + 1 = 14 triangles in the given figure.

Why don't use the angle BJH. JCI?

Don't we have any shortcut formulae for doing this? As it takes time for completing one question, which will consume more time for a single mark.
