Having broken your head over the solution of various logical problems and puzzles, you can, and even need to develop ingenuity in yourself. This is not only a kind of “charging” for the mind, the ingenuity will come in handy in making non -standard decisions.

And no matter how many years you are, it is worthwhile to do all these tasks and puzzles. Not only is it exciting enough, but it will also bring you practical benefits. After all, trained non -trivial thinking will always help a person in any life situations, and even with benefit for himself.
How to connect 9 points 4 lines?
- The task is to connect 9 points 4 lines
Given: 9 points. Connect 9 points 4 in straight lines without tearing the handle or pencil from a sheet of paper. Points are located like this (see drawing):
We denote the separate point in numbers - it is more convenient to solve the problem:
3 4 5
2 9 6
1 8 7
The rules states that the square of 9 points must be connected with 4 lines using only straight lines. Repetitions are not allowed, i.e. Once the drawn line is no longer returned. As we said above, the pencil is torn off from the paper where points are affixed is prohibited.
Clue: It is impossible to unravel the task using simple attempts to connect nine points with four lines using the principle of diagonals and sides of the square - this will require non -standard thinking.
How to connect 9 points 4 lines: answer
- What do we know about how the segments differ from lines or straight lines? The segments are strictly limited by points, while lines and straight lines can be continued endlessly in any direction. There are four such lines in our task, and they can be extended further than the data to us nine points.
Consider the step -by -step solution of the puzzle:
- You should either imagine how the lines will run, or lay them schematically on paper.
- The first will connect The 3rd and 5th, passing through the 4th, will continue above the 6th point.
- Next, the diagonal line will srack after the 6th and 8th and will continue further, somewhat not reaching the 1st point. Thus, the first two lines will be built.
- The next, third line will connect 1st and 3rd through the 2nd point. Thanks to these manipulations, we get a figure in the form of a triangle, in which one peak is at the 3rd point, and the other two are outside the 5th and 1st points.
- The case remains behind the final line, which will connect 3rd, 9th and 7th points.
The sequence of points does not matter, for example, you can change the second and fourth places and so on. And there is absolutely no difference what angle in our square will become the beginning of the construction of the figure in the form of an umbrella.
