Find the number of triangles in the given figure.

22
24
26
28
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.

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

How to find No.of inner nodes?

Susi said:   1 decade ago
I use one formula

Formula is

No.of nodes + 2 (no.of inner nodes)

This formula is obsolutely correct.

These sums are very complicated how to understand them first. Solving is secondary.

@Rahul.

How it is possible that Total number of nodes are lesser than inner nodes?
(1)

Yes I too getting answer as 26 by using above formula please solve this question.

Nayaz said:   12 months ago
How do we know about the inner nodes? Anyone, please explain to me.

Tanvir Aditya said:   2 years ago
According to me, another triangle HFD, AEJ in the given diagram.

Rudra said:   1 decade ago
This might be number of nodes (6)+2*number of inter node (10)+2.

How can we only consider I, L as inner nodes leaving J,K,G,H?
