perpendicular bisector

Draws the perpendicular bisector of a segment. The segment is dened either by its name or by its two

endpoints.

perpen_bisector(segment) or perpen_bisector(point1, point2)

Examples:

perpen_bisector(GC) draws the perpendicular bisector of segment C.

perpen_bisector(GA, GB) draws the perpendicular bisector of segment AB.

perpen_bisector(3+2i, i) draws the perpendicular bisector of a segment whose endpoints have

coordinates (3, 2) and (0, 1); that is, the line whose equation is y=x/3+1.

point2d

Randomly redistributes a set of points such that, for each point, x ∈ [–5,5] and y ∈ [–5,5]. Any further

movement of one of the points will randomly redistribute all of the points with each tap or direction key

press.

point2d(point1, point2, …, pointn)

polar

Returns the polar line of the given point as pole with respect to the given circle.

polar(circle, point)

Example:

polar(circle(x^2+y^2=1),point(1/3,0)) returns x=3

pole

Returns the pole of the given line with respect to the given circle.

pole(circle, line)

Example:

pole(circle(x^2+y^2=1), line(x=3)) returns point(1/3, 0)

power_pc

Given a circle and a point, returns the dierence between the square of the distance from the point to the

circle’s center and the square of the circle’s radius.

powerpc(circle, point)

Example:

powerpc(circle(point(0,0), point(1,1)-point(0,0)), point(3,1)) returns 8
