Find the number of triangles in the given figure.
Answer: Option
Explanation:
The figure may be labelled as shown.
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 and EGI i.e. 4 in number.
The triangles composed of three components each are ACE, AGE and CFD i.e. 3 in number.
There is only one triangle i.e. AHE composed of four components.
Therefore, There are 6 + 4 + 3 + 1 = 14 triangles in the given figure.

Nodes are vertices which are labeled as (A, B, . , I, J).
Such as: A is node similarly I is an internal node.

A doubt in this figure, why we are counting 4 triangles twice. Ex aig in one component and 4 components.

Just to concentrate the figure and count it's twice or thrice then you can solve it.
