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.
// 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.
Throws:
{Error}
If the elements cannot be constructed with the given parent objects an exception is thrown.
Returns:
A JXG.Line object through the given point that is orthogonal to the given line.
