Find the number of triangles in the given figure.

12
18
22
26
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.

What is meant by components ?

Dharshan said:   10 years ago
Is there any formulas to calculate the problem?

Prathap said:   10 years ago
These kind of problems are a kind of dynamic ones hence dealing with formulae can't happen at ease.

Is there any shortcut for these problems to solve?

Midhun Kumar said:   1 decade ago
No short cuts are available till now, we have to solve by ourselves.

Is there any shortcut for counting number of triangle?

By using count only, we can find out the answers for this type of problems.
