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.

From the above figure indicated ay A, B, C, D, and so on..
TTotalNumbers Of Nodes = 16 (A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P).
And Inner Nodes = 4 (M, N, O, P).
So Formula = Total no of Nodes + 2 * (Inner Nodes).
= 16 + 2 * 4.
= 28 Answer.

First, count all nodes A to P is 16.
Then count inner nodes IHMNJGOLPK is 10.
16 + 10 + 2 = 28.
Hope you unterstand.
Then count inner nodes IHMNJGOLPK is 10.
16 + 10 + 2 = 28.
Hope you unterstand.

What is nodes?

This might be number of nodes (6)+2*number of inter node (10)+2.

If you take number of straight line in this figure i.e. 7,
Each line is used to make 4 triangle so total triangle will be 7*4 = 28.
Each line is used to make 4 triangle so total triangle will be 7*4 = 28.

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

The sure solution comes only through a lot of practice.
