Problem Statement
In a regular polygon with sides, diagonals are drawn so that exactly one diagonal emerges from each vertex. We call the length of a diagonal the number of sides of the polygon included between the vertices of the diagonal and which is less than or equal to . If we order the lengths of the diagonals in ascending order, we obtain a succession of numbers . It will be possible to draw diagonals such thata) ?b) ?
