Answer (Detailed Solution Below)

Option 1 : 21

Triangles Question 3 Detailed Solution

Given Figure:

qImage6870999616380ec9a3bbeffe

Now,

Counting the figure separately:

1. Counting the numbers of triangles.

F1 Prashant K 8.2.21 Pallavi D3

The above figure has three triangles. There are three similar figures in the given figure.

So, the below figure has a triangle

F1 Prashant K 8.2.21 Pallavi D4

3 × 3 = 9

Now, after completing the figures as per the question we will count the number of triangles that are made on the edges and a Merging triangle as shown below:

F1 Prashant K 8.2.21 Pallavi D5

There are 4 triangles on the edges as shown above and Two triangles that are TriAOB and TriCOD which are merging triangle.

So, we can say number of traingle = 4 + 2 = 6.

There are two more small similar triangles 

F1 Prashant K 8.2.21 Pallavi D6

so triangle in these will be

3 × 2 = 6 

Thus, the total no of triangle = 9 + 6 + 6 = 21

Hence, the correct answer is "21".

Triangles Question 4:

The number of triangles in the figure is

Triangles Question 15:

How many triangles are there in the given figure?
F1 Souravs SSC 6 12 24 D1

  1. 21
  2. 20
  3. 19
  4. 18

Answer (Detailed Solution Below)

Option 1 : 21

Triangles Question 15 Detailed Solution

The number of triangles in the given figure is shown below:

1) Total triangles = [Number of parts × (1 + Number of parts)] ÷ 2

= [2 × (1 + 2)] ÷ 2

= [2 × 3] ÷ 2

= 6 ÷ 2

= 3

As there are 3 same types of triangles, therefore total number of triangles will be (3 × 3) = 9 

F1 SouravS SSC 2 12 24 D32

2) As marked there are total 12 triangles.

F1 Sourav SSC 6 12 24 Prashant003

Thus, there are total (9 + 12) = 21 triangles.

Hence, "Option 1" is the correct answer.
