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.
