circumcircle(A,B,C)=circumcircle of the triangle ABC.
circumcircle((Pnt or Cplx),(Pnt or Cplx),((Pnt
or Cplx))
Defines a conic by its equation with x,y as default variables
and draws it.
conic(Expr,[LstVar])
ellipse(F1,F2,M)=ellipse focus F1,F2 through M or such as
MF1+MF2=2*a (geo2d) and ellipse(p(x,y)) draws the conic
if deg(p)=2.
ellipse(Pnt(F1),Pnt(F2),(Pnt(M) or Real(a)) y
ellipse(p(x,y))=conic si deg(p)=2.)
excircle(A,B,C) draws the A-excircle of the ABC triangle.
excircle((Pnt or Cplx),(Pnt or Cplx),(Pnt or
Cplx))
hyperbola(F1,F2,M)=hyperbola focus F1,F2 through M or
(|MF1-MF2|=2*a geo2d) and hyperbola(p(x,y)) draws the
conic if deg(p)=2.
hyperbola(Focus(F1),Focus(F2),(Pnt(M) or
Real(a)))
incircle(A,B,C) draws the incircle of the ABC triangle.
incircle((Pnt or Cplx),(Pnt or Cplx),(Pnt or
Cplx))
locus(M,A) draws the locus of M (or locus(d,A) draws the
envelope of d) when A:=element(C) (C is a curve). The
example instructions below must be written in a geometric
level on different lines.
