Element Detail
Semicircle
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "semicircle".

Possible parent array combinations are:
{JXG.Point} p1
{JXG.Point} p2

The result will be a composition of an arc drawn clockwise from p1 and p2 and the midpoint of p1 and p2.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create an arc out of three free points
var p1 = board.create('point', [4.5, 2.0]);
var p2 = board.create('point', [1.0, 0.5]);

var a = board.create('semicircle', [p1, p2]);
