Regular Polygon

The angles have the same angle from the center
Number of angles n
Side length a_n
Number of angles n
Side length a_n
Interior angle phi=360/n
Base angle alpha_n=(1-2/n)*90
Sum of angles (n-2)*pi
Radius of inner circle r_i=a/(2 tan(180/n))
Radius of outer circle r_o=a/(2 sin(180/n))
Area A=n*a*r_i/2
