Answer:
They prove to be a set of regular polygons.
Step-by-step explanation:
The roots of unity can be expressed as:
[tex]z_i,_n=\sqrt[n]{1}[/tex]
There are n solutions for the n-th root of unity, for [tex]i=0,1,2...,n-1[/tex]
All these n solutions are points accross the XY plane, all of them keeping a distance from the center (point [tex](0,0)[/tex]) of 1. They all trace a regular polygon whose circumscribed circumference is of radius 1, too. The number of sides and vertices of this polygon is n.
