regpolygon

In Euclidean geometry, a regular polygon is a polygon that is equiangular
(all angles are equal in measure) and equilateral (all sides have the same
length). This function gives all the possible properties of a regulare
polygon. Moreover, for polygons with 3<=n<=12 sides, will be shown an
animation to how contruct it (exactly or approximately) using ruler and
compass.

Syntax: regpolygon(varargin)

Inputs:
n: sides number, a scalar >=3 (3 by default)
L: side length, a scalar >0 (1 by default)
1 (right tailed)
Outputs:
Sides
Length
Fixed number
Apotema
Inscribed circle area
Height
number of diagonals
Perimeter
Area fixed number (phi)
Area
Circumradius
Circumscribed circle area
Interior angle
Exterior angle
Constructible or not

Example:

Calling on Matlab the function: regpolygon(5)
