altitude(GA,GB,GC) is the form you need to use in
calculations
Further, in many cases the specified parameters in the syntax
below—A, B, C etc.—can be the name of a point (such as
GA) or a complex number representing a point. Thus
angle(A,B,C) could be:
•
angle(GP,GR,GB)
angle(3+2i,1–2i,5+i) or
•
a combination of named points and points defined by a
•
complex number, as in angle(GP,i1–2i,i).
barycenter([point1,coeff1],...) draws the barycenter of point1
with weight coeff1...
barycenter([Pnt,Real],[Pnt,Real],[Pnt,Real])
Gives the coordinates of the center of circle A.
center(A)
Returns the point M such that (z-a)=k*(z-b) and z=affix of M
(MA=k*MB).
division_point(Pnt or Cplx(a),Pnt or
Cplx(b),Cplx(k))
Shows a point chosen on a curve or a real chosen in an
interval
element((Curve or Real_interval),[Val])
With 2 arguments gives the intersection of 2 curves or
surfaces as a vector. If a third argument is given, the
intersection returned is the one closest to that argument.
