Find the number of triangles in the given figure.

8
10
12
14
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.

@ Priyanka.

This formula doesn't work as, there is one more triangle present in the figure and it is AHE (That comprises of the four components).

@Priyanka.

Is there any standard such formula. I tried this formula for a structure a star with in a circle. It didn't work. Please tell me?

Thanks Priyanka.

Priyanka said:   1 decade ago
No. of total nodes + 2(no. of inner nodes)
Here,
Total no. of nodes=10
No. of inner nodes(i and j)=2
10+2(2)=14

Is there any shortcut or trick to solve above question because we have to solve these question in 1 minutes in our entrance exam and its seems very difficult?
