Find the number of triangles in the given figure.

12
18
22
26
Answer: Option
Explanation:

The figure may be labelled as shown.

The simplest triangles are AHB, GHI, BJC, GFE, GIE, IJE, CEJ and CDE i.e. 8 in number.

The triangles composed of two components each are HEG, BEC, HBE, JGE and ICE i.e. 5 in number.

The triangles composed of three components each are FHE, GCE and BED i.e. 3 in number.

There is only one triangle i.e. AGC composed of four components.

There is only one triangle i.e. AFD composed of nine components.

Thus, there are 8 + 5 + 3 + 1 + 1 = 18 triangles in the given figure.

Please anyone tell me the correct way to solve this.

Total no nodes (8) + 2 * (5) inner nodes (h, b, g, c, e) = 18.

I don't understand the concept of the triangle components.

Please, anybody, give me some ideas.

I don't think so, that two components forming with 4 letters as HBE &BEC both are two components triangle but HBE made with 5 letters and BEC made with 4 letters.

The simple triangle means forming with 3 letters.

Two components forming with 4 letters.
Three components forming with 5 letters.
