## Logical puzzle

For puzzle enthusiasts, a **challenge** like this is a real "doozy" and it may seem impossible to solve at first glance - but there is a way.

In the image given, there is a triangle made up of 3 matches. Your task is to **make a perfect square** by moving only one of the matches.

Small hint: in addition to carefully studying the matches, carefully study the words of the challenge itself. There is no time limit for this **puzzle**: logical thinking is more important than speed here.

## Solution

While this game is not intended to **measure** IQ, only true lateral thinkers will succeed in solving this puzzle. The critical clue lies in the wording of the challenge.

And here's one last clue: mathematics is the right way to **solve** this puzzle. If you wish, take a few more moments to think about it.

So, here's the solution: you need to move a matchstick to form the number "4". Of course, you will not have created a physical square: the trick was to realize that the square had to be "mental one". 4 is the square of 2!

In mathematics, a "perfect square" is defined as an integer that can be expressed as the square of another number; in simple words, a number whose square root is an integer. Sometimes you need to think "outside the box". **Did you solve this puzzle?**
