Element Detail
PerpendicularSegment
A perpendicular is a composition of two elements: a line segment and a point. The line segment is orthogonal
to a given line and contains a given point and meets the given line in the perpendicular point.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "perpendicularsegment".
- Possible parent array combinations are:
-
{JXG.Line} l
{JXG.Point} 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:
- {Error}
- 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 segment is orthogonal to the given line and meets it in the returned point.
- Examples:
// 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('perpendicularsegment', [l1, p3]);
