This brain teaser asks you to think quickly and analytically. Your task is to discover all the triangles in the image below in five seconds.
In addition to being a form of entertainment, these tests could also have long-term health benefits, helping to keep the brain healthier for longer.
The term intelligence quotient (IQ) was invented in 1912 by psychologist Wiliam Stern and comes from the German concept of «inteligenzquotient». Later, Professor Howard Gardner developed the theory of multiple intelligences. According to him, there are eight types of intelligence: intrapersonal, interpersonal, bodily, spatial, naturalistic, linguistic, musical, and logical-mathematical.
For the latter, we are talking about that type of logical and analytical thinking that mathematicians and physicists especially have. Those who possess such intelligence cope much better with symbols, numbers, and graphic representations.
We have prepared a quick challenge for you! Look carefully at the image above and guess how many triangles are actually in the picture.
You only have 5 seconds to find all the triangles. Did you say three? Then count again! The correct answer is not even four. Look carefully at the picture! Have you discovered all the triangles in less than five seconds? If you didn’t manage to find them all, you have the correct answer in the photo gallery below.
