54 Geometry

Example:

rotate(GA, angle(GB, GC, GD),GK) rotates the

geometric object labeled K, about point A, through an angle

equal to ∡ CBD.

Dilation

Dilates a geometric object, with respect to a center point, by

a scale factor.

homothety(point, realk, object)

Example:

homothety(GA, 2, GB) creates a dilation centered at

point A that has a scale factor of 2. Each point P on geometric

object B has its image P’ on ray AP such that AP’=2AP.

Similarity

Dilates and rotates a geometric object about the same center

point.

similarity(point, realk, angle, object)

Example:

similarity(0, 3, angle(0,1,i),point(2,0))

dilates the point at (2,0) by a scale factor of 3 (a point at

(6,0)), then rotates the result 90° counterclockwise to create a

point at (0, 6).

Projection

Draws the orthogonal projection of a point onto a curve.

projection(curve, point)

Inversion

Draws the inversion of a point, with respect to another point,

by a scale factor.

inversion(point1, realk, point2)

Example:

inversion(GA, 3, GB) draws point C on line AB such

that AB*AC=3. In this case, point A is the center of the

inversion and the scale factor is 3. Point B is the point whose

inversion is created.
