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]);
