Find the number of triangles in the given figure.

12
13
14
15
Explanation:

The figure may be labelled as shown.

The simplest triangles are ABF, BIC, CIH, GIH, FGE and AFE i.e. 6 in number.

The triangles composed of two components each are ABE, AGE, BHF, BCH, CGH and BIE i.e. 6 in number.

The triangles composed of three components each are ABH, BCE and CDE i.e. 3 in number.

Hence, the total number of triangles in the figure = 6 + 6 + 3 = 15.

Total no of nodes = 9.
No of inner nodes = 3.
Formula:
So, total no of nodes + 2 ( no of inner nodes) = 9 + 2(3) = 15.

What is meant by components how they are changing?

There are six simple triangles and six composed of two components.

@Ananya Saha.

ABG, BFG, EFH are not triangles.
