Element Detail
Normal
A normal is a line through a given point on a element of type line, circle, curve, or turtle and orthogonal to that object.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "normal".

Possible parent array combinations are:
{JXG.Line|JXG.Circle|JXG.Curve|JXG.Turtle} o
{JXG.Point} p

The constructed line contains p which lies on the object and is orthogonal to the tangent to the object in the given point.


{Glider} p

Works like above, however the object is given by Glider#slideObject.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a normal to a circle.
var p1 = board.create('point', [2.0, 2.0]);
var p2 = board.create('point', [3.0, 2.0]);
var c1 = board.create('circle', [p1, p2]);

var norm1 = board.create('normal', [c1, p2]);
