186 Geometry

If GA is the point at (0, 0), GB is the point at (1, 0), and GC

is defined as square(GA, GB-GA), then perimeter(GC)

returns 4.

radius

Returns the radius of a circle.

radius(circle)

Example:

If GA is the point at (0, 0), GB is the point at (1, 0), and GC

is defined as circle(GA, GB-GA), then radius(GC) returns 1.

Test

is_collinear

Takes a set of points as argument and tests whether or not they

are collinear. Returns 1 if the points are collinear and 0

otherwise.

is_collinear(point1, point2, …, pointn)

Example:

is_collinear(point(0,0), point(5,0),

point(6,1)) returns 0

is_concyclic

Takes a set of points as argument and tests if they are all on

the same circle. Returns 1 if the points are all on the same

circle and 0 otherwise.

is_concyclic(point1, point2, …, pointn)

Example:

is_concyclic(point(-4,-2), point(-4,2),

point(4,-2), point(4,2)) returns 1

is_conjugate

Tests whether or not two points or two lines are conjugates for

the given circle. Returns 1 if they are and 0 otherwise.

is_conjugate(circle, point1, point2) or

is_conjugate(circle, line1, line2)
