Answer: No es posible (It is not possible)
Step-by-step explanation:
The question in english is as follows:
Is it possible to draw 9 line segments so that each segment crosses exactly 1 of the other segments?
A necessary condition for two lines to intersect is that they must be in the same plane (they must be coplanar), being their intersection a single point.
Now, if we want several lines to intersect only once, we need to have an <u>even number</u> of line segments. However, this is not the case because <u>9 is odd.
</u>
Therefore, it is not possible.
