Class NonReflexAngle

JXG.GeometryElement
   ↳ JXG.Curve
      ↳ Sector
         ↳ Angle
               ↳ NonReflexAngle

A non-reflex angle is the acute or obtuse instance of an angle. It is defined by a center, one point that defines the radius, and a third point that defines the angle of the sector.

Defined in: sector.js.
Extends Angle.

Class Detail
NonReflexAngle(p1,p2,p3)
Parameters:
{JXG.Point_JXG.Point_JXG.Point} p1,p2,p3
. Minor sector is a sector of a circle around p1 having measure less than or equal to 180 degrees (pi radians) and starts at p2. The radius is determined by p2, the angle by p3.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a non-reflex angle out of three free points
var p1 = board.create('point', [5.0, 3.0]),
    p2 = board.create('point', [1.0, 0.5]),
    p3 = board.create('point', [1.5, 5.0]),

    a = board.create('nonreflexangle', [p1, p2, p3], {radius: 2}),
    t = board.create('text', [4, 4, function() { return JXG.toFixed(a.Value(), 2); }]);
