Element RadicalAxis
JXG.GeometryElement
↳ JXG.Line
↳ RadicalAxis
This element is used to provide a constructor for the radical axis with respect to two circles with distinct centers.
The angular bisector of the polar lines of the circle centers with respect to the other circle is always the radical axis.
The radical axis passes through the intersection points when the circles intersect.
When a circle about the midpoint of circle centers, passing through the circle centers, intersects the circles, the polar lines pass through those intersection points.
Defined in: line.js.

Element Detail
RadicalAxis
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "radicalaxis".
- Possible parent array combinations are:
-
{JXG.Circle} circle
- Circle one of the two respective circles.
-
{JXG.Circle} circle
- Circle the other of the two respective circles.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
// Create the radical axis line with respect to two circles
var board = JXG.JSXGraph.initBoard('7b7233a0-f363-47dd-9df5-5018d0d17a98', {boundingbox: [-1, 9, 9, -1], axis: true, showcopyright: false, shownavigation: false});
var p1 = board.create('point', [2, 3]);
var p2 = board.create('point', [1, 4]);
var c1 = board.create('circle', [p1, p2]);
var p3 = board.create('point', [6, 5]);
var p4 = board.create('point', [8, 6]);
var c2 = board.create('circle', [p3, p4]);
var r1 = board.create('radicalaxis', [c1, c2]);
