The problem with the pool table: Solución

By raising the issue of the pool table, that is to hit one of the two balls that are on the table (A for example) , so that it impacts the other (la B) previously given in one of the bands (edges) Table, flipping the closed problem to a simple bounce case.

We can generalize the problem considering that you can give, before impact with the second ball, a given number of impacts with the bands (lateral edges) Table.

Determinación de un segmento conocido su punto medio [Statement]

An interesting metric geometry problem that can enlighten the way to find solutions is to determine a segment of known its midpoint with additional restrictions.

And that a segment is determined by its ends (colon), in the plane need four values (simple data) to set their Cartesian coordinates.
