Geometry 175
Example
rhombus(GA, GB, angle(GC, GD, GE)) draws a
rhombus on segment AB such that the angle at vertex A has
the same measure as ∡ DCE.
right_triangle
Draws a right triangle given two points and a scale factor.
One leg of the right triangle is defined by the two points, the
vertex of the right angle is at the first point, and the scale
factor multiplies the length of the first 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.
square
Draws a square, given two consecutive vertices as points.
square(point1, point2)
Example:
Example: square(0, 3+2i, p, q) draws a square with vertices
at (0, 0), (3, 2), (1, 5), and (-2, 3). The last two vertices are
computed automatically and are saved into the CAS variables
p and q.
triangle
Draws a triangle, given its three vertices.
triangle(point1, point2, point3)
Example:
triangle(GA, GB, GC) draws ΔABC.
