Polygon

equilateral_triangle

Draws an equilateral triangle defined by one of its sides; that

is, by two consecutive vertices. The third point is calculated

automatically, but is not defined symbolically. If a lowercase

variable is added as a third argument, then the coordinates

of the third point are stored in that variable. The orientation of

the triangle is counterclockwise from the first point.

equilateral_triangle(point1, point2) or

equilateral_triangle(point1, point2, var)

Examples:

equilateral triangle(0,6) draws an equilateral

triangle whose first two vertices are at (0, 0) and (6,0); the

third vertex is calculated to be at (3,3*√3).

equilateral triangle(0,6, v) draws an equilateral

triangle whose first two vertices are at (0, 0) and (6,0); the

third vertex is calculated to be at (3,3*√3) and these

coordinates are stored in the CAS variable v. In CAS view,

entering v returns point(3*(√3*i+1)), which is equal to

(3,3*√3).

hexagon

Draws a regular hexagon defined by one of its sides; that is,

by two consecutive vertices. The remaining points are

calculated automatically, but are not defined symbolically.

The orientation of the hexagon is counterclockwise from the

first point.

hexagon(point1, point2) or hexagon(point1,

point2, var1, var2, var3, var4)

Examples:

hexagon(0,6) draws a regular hexagon whose first two

vertices are at (0, 0) and (6, 0).

hexagon(0,6, a, b, c, d) draws a regular hexagon

whose first two vertices are at (0, 0) and (6, 0) and stores the

other four points into the CAS variables a, b, c, and d. You do

not have to define variables for all four remaining points, but

the coordinates are stored in order. For example,

hexagon(0,6, a) stores just the third point into the CAS

variable a.
