Find the number of triangles in the given figure.

11
13
15
17
Answer: Option
Explanation:

The figure may be labelled as shown.

The simplest triangles are AKI, AIL, EKD, LFB, DJC, BJC, DHC and BCG i.e. 8 in number.

The triangles composed of two components each are AKL, ADJ, AJB and DBC i.e. 4 in number.

The triangles composed of the three components each are ADC and ABC i.e. 2 in number.

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

Thus, there are 8+ 4 + 2 + 1= 15 triangles in the figure.

Here, we have to calculate the number of triangles in the given figure as;

First, we have to count how many 1unit triangles are there; in this figure 1unit =8 triangles are there.

Likewise, 2 unit=4 triangles are there.

3unit = 2 triangles.

4unit = 1triangle.

At last, we have to add these numbers to find a total number of triangles in the given figure:.

8 + 4 + 2 + 1 = 15. Therefore, 15 triangles are there in the given figure.

Anyone explain the answer in detail.

4 triangles are outside(dek,cdh,bcg,bfl),
8 triangles in middle(kdcbl),
3 triangles in upper base(akl),
Total 8+4+3 = 15.

Instead of denoting letter for the points, correct formula to solve it.

Anyone exact formula for these type problems?

I can't understand what's the procedure behind it?
