Draws a line through A that crosses segment BC at right
angles.
altitude(A,B,C)
Draws the bisector of the angle (AB,AC) given by 3 points
A,B,C.
bisector((Pnt(A) or Cplx),(Pnt(B) or
Cplx),(Pnt(C) or Cplx))
Draws the exterior bisector of the angle (AB,AC) given by 3
points A,B,C.
exbisector((Pnt(A) or Cplx),(Pnt(B) or
Cplx),(Pnt(C) or Cplx))
half_line(A,B) draws the half-line AB with A as origin
half_line((Pnt or Cplx),(Pnt or Cplx))
line(A,B) or line(a*x+b*y+c=0) or
line(a*x+b*y+c*z+d=0,aa*x+bb*y+cc*z+dd=0) draws
the line AB in the plane or in the 3D space. line(A,slope=m)
draws the line going through A with slope m or of equation
the argument in the plane or in 3D space.
line(Pnt||Cplx||Eq,[Pnt||slope||Var])
median_line(A,B,C) draws the median-line through A of the
triangle ABC
median_line((Pnt or Cplx),(Pnt or Cplx),(Pnt
or Cplx))
parallel(A,D) (resp parallel(A,P) or parallel(A,D,DD)) draws
the line (resp plane) through A parallel to the line D (resp
parallel to the plane P or to the lines D,DD) and, parallel(d,D)
draws the plane through d parallel to the line D.
