Class Detail
Slopetriangle(t, li,)
Parameters:
{JXG.Line} t
A tangent based on a glider on some object, e.g. curve, circle, line or turtle.


{JXG.Line_JXG.Point} li,
p A line and a point on that line. The user has to take care that the point is a member of the line.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown. Parameter options:
Examples:
// Create a slopetriangle on a tangent
var f = board.create('plot', ['sin(x)']),
    g = board.create('glider', [1, 2, f]),
    t = board.create('tangent', [g]),

    st = board.create('slopetriangle', [t]);


				
				
// Create a on a line and a point on that line
var p1 = board.create('point', [-2, 3]),
    p2 = board.create('point', [2, -3]),
    li = board.create('line', [p1, p2]),
    p = board.create('glider', [0, 0, li]),

    st = board.create('slopetriangle', [li, p]);


				
                
Field Detail
{Line} baseline
Attributes for the base line.
Defined in: options.js.

{Point} basepoint
Attributes for the base point.
Defined in: options.js.

{Point} glider
Attributes for the gliding helper point.
Defined in: options.js.

{Label} label
Attributes for the slope triangle label.
