---------------
The internal angle of a regular polygon of n sides is
180*(n-2)/n degrees = A
---------------------
The angle from the center to 2 adjacent vertices is
180 - A
--------
The bisector from the center to a side forms 2 congruent right triangles.
The length of the side is 2r*sin(A/2)
= 10sin(A/2)
= 10sin(90(n-2)/n)
