generalising GCSE questions (6)

a question from Edexcel asks about the diagonal length of any square

this can be developed to consider the longest diagonal of even sided regular polygons

why is the hexagon an easy shape to consider?
calculations will involve angles in regular polygons and trigonometry
 a neat generalisation
another neat generalisation but not so easy to establish
