Find the number of triangles in the given figure.
Answer: Option
Explanation:
The figure may be labelled as shown.
The simplest triangles are AGH, GFO, LFO, DJK, EKP, PEL and IMN i.e. 7 in number.
The triangles having two components each are GFL, KEL, AMO, NDP, BHN, CMJ, NEJ and HFM i.e. 8 in number.
The triangles having three components each are IOE, IFP, BIF and CEI i.e. 4 in number.
The triangles having four components each are ANE and DMF i.e. 2 in number.
The triangles having five components each are FCK, BGE and ADL i.e. 3 in number.
The triangles having six components each are BPF, COE, DHF and AJE i.e. 4 in number.
Total number of triangles in the figure = 7 + 8 + 4 + 2 + 3 + 4 = 28.

If you suggest some short cut method for solving analytical problem (non-verbal) then it is very helpful to us.

Very useful this site.

This method is a bit time-taking but cont. Practice will make you perfect!
Name all the points, for eg. Point A point B etc. And start counting no. Of triangles originatin from the points named.
When you have counted all the tri. Originating from all the points, eliminate the same triangles.
The remaining is the answer.
Hope this will help!

I use one formula
Formula is
No.of nodes + 2 (no.of inner nodes)
This formula is obsolutely correct.

How can you apply this formula here.

Can we apply 'No.of nodes + 2 (no.of inner nodes) ' formula another Triangles?
How to find No.of inner nodes?

Here no.of Nodes are 16 (A to P). My question the what are all inner nodes i.e no.of inner nodes also how can we consider that as inner nodes ?

@Azhar.
Here the no.of inner nodes are 10, whereas the total no.of nodes are 16 as you said. You just count you can come 2 know the inner nodes where and all 2 or 3 lines are joining that will become your inner node.
@Suresh.
I'm not getting the answer as 28 if we apply that formula. I'm getting it's 26.

For these type of questions the only way of shortcut is. Practice. Don't depend on any other shortcuts. Those might be correct only for few sums.
