This element is used to provide a constructor for a perpendicular.
Defined in: Composition.js.

Class Summary
Constructor Attributes Constructor Name and Description
 
A perpendicular is a composition of two elements: a line and a point.
Class Detail
Perpendicular(l,p)
A perpendicular is a composition of two elements: a line and a point. The line is orthogonal to a given line and contains a given point and meets the given line in the perpendicular point.
// Create a perpendicular
var p1 = board.create('point', [0.0, 2.0]);
var p2 = board.create('point', [2.0, 1.0]);
var l1 = board.create('line', [p1, p2]);

var p3 = board.create('point', [3.0, 3.0]);
var perp1 = board.create('perpendicular', [l1, p3]);

				
				
				
				
					
						
Parameters:
{JXG.Line_JXG.Point} l,p
The perpendicular line will be orthogonal to l and will contain p. The perpendicular point is the intersection point of the two lines.
Throws:
{Exception}
If the elements cannot be constructed with the given parent objects an exception is thrown.
Returns:
An array containing two elements: A JXG.Line object in the first component and a JXG.Point element in the second component. The line is orthogonal to the given line and meets it in the returned point.
