Question

Es posible dibujar 9 segmentos de línea de manera que cada segmento interseque exactamente 1 de los otros segmentos?

Answer 1

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 even number of line segments. However, this is not the case because 9 is odd.

Therefore, it is not possible.
