Formula description

In geometry a polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). The area of a regular n-gon, inscribed in a unit-radius circle, with side s and interior angle theta can also be expressed trigonometrically as the formula.
