Bisector

Given three points, creates the bisector of the angle dened by the three points whose vertex is at the rst

point. The angle does not have to be drawn in the Plot view.

bisector(point1, point2, point3)

Examples:

bisector(A,B,C) draws the bisector of ∡BAC.

bisector(0,-4i,4) draws the line given by y=–x

Polygon

Triangle

Draws a triangle, given its three vertices.

triangle(point1, point2, point3)

Example:

triangle(GA, GB, GC) draws ΔABC.

Isosceles Triangle

Draws an isosceles triangle dened by two of its vertices and an angle. The vertices dene one of the two

sides equal in length and the angle denes the angle between the two sides of equal length. Like

equilateral_triangle, you have the option of storing the coordinates of the third point into a CAS

variable.

isosceles_triangle(point1, point2, angle)

Example:

isosceles_triangle(GA, GB, angle(GC, GA, GB) denes an isosceles triangle such that one

of the two sides of equal length is AB, and the angle between the two sides of equal length has a measure

equal to that of ∡ACB.

Right Triangle

Draws a right triangle given two points and a scale factor. One leg of the right triangle is dened by the two

points, the vertex of the right angle is at the rst point, and the scale factor multiplies the length of the rst

leg to determine the length of the second leg.

right_triangle(point1, point2, realk)

Example:

right_triangle(GA, GB, 1) draws an isosceles right triangles with its right angle at point A, and with

both legs equal in length to segment AB.

Quadrilateral

Draws a quadrilateral from a set of four points.

quadrilateral(point1, point2, point3, point4)

Example:

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