Element RegularPolygon
JXG.GeometryElement
↳ JXG.Polygon
↳ Polygon
↳ RegularPolygon
A regular polygon is a polygon that is
direct equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
It needs two points which define the base line and the number of vertices.
Defined in: polygon.js.

Element Detail
RegularPolygon
Constructs a regular polygon. It needs two points which define the base line and the number of vertices, or a set of points.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "regularpolygon".
- Possible parent array combinations are:
-
{JXG.Point} p1
{JXG.Point} p2
{Number} n
- The constructed regular polygon has n vertices and the base line defined by p1 and p2.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
var p1 = board.create('point', [0.0, 2.0]);
var p2 = board.create('point', [2.0, 1.0]);
var pol = board.create('regularpolygon', [p1, p2, 5]);
var p1 = board.create('point', [0.0, 2.0]);
var p2 = board.create('point', [4.0,4.0]);
var p3 = board.create('point', [2.0,0.0]);
var pol = board.create('regularpolygon', [p1, p2, p3]);
// Line of reflection
var li = board.create('line', [1,1,1], {strokeColor: '#aaaaaa'});
var reflect = board.create('transform', [li], {type: 'reflect'});
var pol1 = board.create('polygon', [[-3,-2], [-1,-4], [-2,-0.5]]);
var pol2 = board.create('polygon', [pol1, reflect]);
