The simplest triangles are AHG, AIG, AIB, JFE, CJE, and CED i.e. 6 in number.

The triangles composed of two components each are ABG, CFE, ACJ, EGI i.e. 4 in number.

The triangles composed of three components each are ACE, AGE, CFD i.e. 3 in number.

There is only one triangle AHE composed of four components.

So, total = 6 + 4 + 3 + 1 = 14
