Geometry

polygon

Draws a polygon from a set of vertices.

polygon(point1, point2, …, pointn)

Example:

polygon(GA, GB, GD) draws ΔABD

quadrilateral

Draws a quadrilateral from a set of four points.

quadrilateral(point1, point2, point3, point4)

Example:

quadrilateral(GA, GB, GC, GD) draws quadrilateral

ABCD.

rectangle

Draws a rectangle given two consecutive vertices and a point

on the side opposite the side defined by the first two vertices

or a scale factor for the sides perpendicular to the first side.

As with many of the other polygon commands, you can

specify optional CAS variable names for storing the

coordinates of the other two vertices as points.

rectangle(point1, point2, point3) or
rectangle(point1, point2, realk)

Examples:

rectangle(GA, GB, GE) draws a rectangle whose first

two vertices are points A and B (one side is segment AB).
Point E is on the line that contains the side of the rectangle
opposite segment AB.

rectangle(GA, GB, 3, p, q) draws a rectangle whose

first two vertices are points A and B (one side is segment AB).
The sides perpendicular to segment AB have length 3*AB.
The third and fourth points are stored into the CAS variables
p and q, respectively.

rhombus

Draws a rhombus, given two points and an angle. As with

many of the other polygon commands, you can specify

optional CAS variable names for storing the coordinates of

the other two vertices as points.

rhombus(point1, point2, angle)
