ellipse

Draws an ellipse, given the foci and either a point on the ellipse or a scalar that is one half the constant sum of the distances from a point on the ellipse to each of the foci.

ellipse(point1, point2, point3) or ellipse(point1, point2, realk)

Examples:

ellipse(GA, GB, GC) draws the ellipse whose foci are points A and B and which passes through point C.

ellipse(GA, GB, 3) draws an ellipse whose foci are points A and B. For any point P on the ellipse, AP+BP=6.

excircle

Draws one of the excircles of a triangle, a circle tangent to one side of the triangle and also tangent to the extensions of the other two sides.

excircle(point1, point2, point3)

Example:

excircle(GA, GB, GC) draws the circle tangent to BC and to the rays AB and AC.

hyperbola

Draws a hyperbola, given the foci and either a point on the hyperbola or a scalar that is one half the constant difference of the distances from a point on the hyperbola to each of the foci.

hyperbola(point1, point2, point3) or hyperbola(point1, point2, realk)

Examples:

hyperbola(GA, GB, GC) draws the hyperbola whose foci are points A and B and which passes through point C.

hyperbola(GA, GB, 3) draws a hyperbola whose foci are points A and B. For any point P on the hyperbola, AP- BP=6.
