Element Detail
Circumcenter
A circumcenter is given by three points which are all lying on the circle with the
constructed circumcenter as the midpoint.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "circumcenter".
- Possible parent array combinations are:
-
{JXG.Point} p1
{JXG.Point} p2
{JXG.Point} p3
- The constructed point is the midpoint of the circle determined by p1, p2, and p3.
- Throws:
- {Error}
- 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 p3 = board.create('point', [3.0, 3.0]);
var cc1 = board.create('circumcenter', [p1, p2, p3]);
