Element Arc

JXG.GeometryElement
   ↳ JXG.Curve
      ↳ Curve
            ↳ Arc

An arc is a segment of the circumference of a circle. It is defined by a center, one point that defines the radius, and a third point that defines the angle of the arc.

Defined in: arc.js.
Extends Curve.

Element Detail
Arc
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "arc".

Possible parent array combinations are:
{JXG.Point} p1
{JXG.Point} p2
{JXG.Point} p3

The result will be an arc of a circle around p1 through p2. The arc is drawn counter-clockwise from p2 to p3.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create an arc out of three free points
var p1 = board.create('point', [2.0, 2.0]);
var p2 = board.create('point', [1.0, 0.5]);
var p3 = board.create('point', [3.5, 1.0]);

var a = board.create('arc', [p1, p2, p3]);

				
                
Field Detail
{JXG.Point} anglepoint
The point defining the arc's angle.

{JXG.Point} center
Center of the arc.

{JXG.Point} radiuspoint
Point defining the arc's radius.
Method Detail
{Number} getRadius()
Deprecated:
Use Arc#Radius
Returns:
{Number}

{Boolean} hasPointSector(x, y)
Checks whether (x,y) is within the sector defined by the arc.
Parameters:
{Number} x
Coordinate in x direction, screen coordinates.
{Number} y
Coordinate in y direction, screen coordinates.
Returns:
{Boolean} True if (x,y) is within the sector defined by the arc, False otherwise.

{Number} Radius()
Determines the arc's current radius. I.e. the distance between Arc#center and Arc#radiuspoint.
Returns:
{Number} The arc's radius

{Number} Value()
Returns the length of the arc.
Returns:
{Number} The arc length
