orthocenter

Returns the orthocenter of a triangle; that is, the intersection of

the three altitudes of a triangle. The argument can be either

the name of a triangle or three non-collinear points that define

a triangle. In the latter case, the triangle does not need to be

drawn.

orthocenter(triangle) or orthocenter(point1,

point2, point3)

Example: orthocenter(0,4i,4) returns (0,0)

perpendicular bisector

Draws the perpendicular bisector of a segment. The segment

is defined 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 re-distributes 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 re-distribute 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
