Perpendicular

Similar to is_orthogonal. Tests whether or not two lines are perpendicular.

is_perpendicular(line1, line2)

Isosceles

Takes three points and tests whether or not they are vertices of a single isosceles triangle. Returns 0 if they

are not. If they are, returns the number order of the common point of the two sides of equal length (1, 2, or

3). Returns 4 if the three points form an equilateral triangle.

is_isosceles(point1, point2, point3)

Example:

is_isoscelesl(point(0,0), point(4,0), point(2,4)) returns 3.

Equilateral

Takes three points and tests whether or not they are vertices of a single equilateral triangle. Returns 1 if they

are and 0 otherwise.

is_equilateral(point1, point2, point3)

Example:

is_equilateral(point(0,0), point(4,0), point(2,4)) returns 0.

Parallelogram

Tests whether or not a set of four points are vertices of a parallelogram. Returns 0 if they are not. If they are,

then returns 1 if they form only a parallelogram, 2 if they form a rhombus, 3 if they form a rectangle, and 4 if

they form a square.

is_parallelogram(point1, point2, point3, point4)

Example:

is_parallelogram(point(0,0), point(2,4), point(0,8), point(-2,4)) returns 2.

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)

Other Geometry functions

The following functions are not available from a menu in the Geometry app, but are available from the Catlg

menu.

aix

Returns the coordinates of a point or both the x- and y-lengths of a vector as a complex number.

affix(point) or affix(vector)

Example:

If GA is a point at (1, –2), then affix(GA) returns 1–2i.
