Class Detail
RegularPolygon(p1,p2,n)
Constructs a regular polygon. It needs two points which define the base line and the number of vertices, or a set of points.
- Parameters:
- {JXG.Point_JXG.Point_Number} p1,p2,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]);
