Triangles MCQ Quiz - Objective Question with Answer for Triangles - Download Free PDF

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

As marked, there are a total of 45 triangles.

Hence, "Option 4" is the correct answer.

The number of the triangles in the given figure will be:

Thus, the number of triangle is "17".

Hence, the correct answer is "Option 3".

Given Figure:

Now,

Counting the figure separately:

1. Counting the numbers of triangles.

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

So, the below figure has a triangle

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:

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 

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".

Total number of triangle is:

Hence, the correct answer is "Option 2'.

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

Thus, there are a total of 12 triangles.

Hence, "Option 4" is the correct answer.

The triangles in the given figure are:

Thus, the figure has 22 triangles.

Hence, "Option 2" is the correct answer.

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

As marked, there are a total of 45 triangles.

Hence, "Option 4" is the correct answer.

Total number of triangle is:

Hence, the correct answer is "Option 2'.

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

Thus, there are a total of 12 triangles.

Hence, "Option 4" is the correct answer.

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

Thus, as marked there are a total of 7 triangles in the given figure.

Hence, "Option 2" is the correct answer.

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

Thus, as marked there are a total of 25 triangles in the given figure.

Hence, "Option 2" is the correct answer.

Total number of triangles is:

Thus, total of number is 7.

Hence, the correct answer is "Option 2".

The number of triangles in the figure is 9

Hence, the correct answer is "Option 4".

The triangles in give figure is:

Thus, the total triangles is 17.

Hence, the correct answer is "Option 3".

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 

2) As marked there are total 12 triangles.

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

Hence, "Option 1" is the correct answer.
