Element Detail
Parallelogram
Constructs a parallelogram. As input, three points or coordinate arrays are expected.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "parallelogram".
- Possible parent array combinations are:
-
{JXG.Point|Array} p1
{JXG.Point|Array} p2
{JXG.Point|Array} p3
- The parallelogram is a polygon through the points [p1, p2, pp, p3], where pp is a parallelpoint, available as sub-object parallelogram.parallelPoint.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
var p1 = board.create('point', [-3, -4]);
var p2 = board.create('point', [3, -1]);
var p3 = board.create('point', [-2, 0]);
var par = board.create('parallelogram', [p1, p2, p3], {
hasInnerPoints: true,
parallelpoint: {
size: 6,
face: '<<>>'
}
});
Field Detail
parallelPoint
Parallel point which makes the quadrilateral a parallelogram. Can also be accessed with
parallelogram.vertices[2].
