Element ReflexAngle
JXG.GeometryElement
↳ JXG.Curve
↳ Sector
↳ Angle
↳ ReflexAngle
A reflex angle is the neither acute nor 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.

Element Detail
ReflexAngle
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "reflexangle".
- Possible parent array combinations are:
-
{JXG.Point} p1
{JXG.Point} p2
{JXG.Point} 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('reflexangle', [p1, p2, p3], {radius: 2}),
t = board.create('text', [4, 4, function() { return JXG.toFixed(a.Value(), 2); }]);
