1. Visual Brain Teaser: How many triangles are in this figure?

There are two different claims about the correct answer! Find the right result and end the discussion.

billiards balls brain question

The number of triangles forms of 1 unit: 16

The number of triangles forms of 4 units: 7

The number of triangles forms of 9 units: 3

The number of triangles forms of 19 units: 1

The answer is 27 triangles.

2. Visual Attention Question: Which balls you should put in the hole in order to total 30?

This is a question that practical people can solve easily.

Visual Brain question 1

This question cannot be solved mathematically. This is because the sum of three odd numbers cannot be an even number.

What you need to measure here is your attention!

If you place balls 11 and 13 into the holes, you get 24.

Then, if you put ball 9 upside down in the hole, you get 24 + 6 = 30.

3. Visual Brain Teaser: Which one is the air view of the tower on the left?

Visual Brain question 2

First of all, let's look at the picture on the left. The top layer is orange. Here, we can eliminate option C directly.

The purple layer underneath will not be visible because it is the same size as the top one.

The small circle below will not be seen from the top of the mould.

Beneath the small orange circle is a large purple circle. This is the second circle that will appear after the initial orange circle and will appear as a thin purple line.

A slightly larger orange circle than the purple one is just below it. This will appear on the outside as the largest circle in our painting.

Therefore, the answer is A.

4. Visual Brain Teaser: When looking at the image on the left, which image on the right is the correct birds-eye view?

If you can find the answer to this question, you have strong visual perception skills.

Visual Brain question 2

If you look at the right side of A, you’ll identify the image on the right.

The correct answer is A.

5. Visual Brain Teaser: Which shadow corresponds to the image on the left?

6. Visual Brain Teaser: View the blocks on the left from the orange point and direction of the arrow. Which image on the right is the correct view?

Visual Brain question 4

Let's answer the question step by step.

We start at the orange spot and look at the blocks.

There are four blocks at the base.

There are two blocks on the right on the top floor. This eliminates option C.

If we go up one more floor, we see only the second block on the right.

So the answer is D.
