Incircle

An incircle is a circle that is

tangent to each of a

polygon’s sides. The HP

Prime can draw an incircle

that is tangent to the sides of

a triangle.

Tap at each vertex of the

triangle, pressing

after each tap.

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.

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.
