<p>the number of sides approaches infinity, the xth shortest diagonal approaches the length . Additionally, the formula for the shortest diagonal simplifies in the case of x = 1:</p>

:</p>

<p>If the number of sides is even, the longest diagonal will be equivalent to the diameter of the polygon's <a href="page.php?w=circumcircle">circumcircle</a> because the long diagonals all intersect each other at the polygon's center.</p>
