constructions

Macros constructing associated points.

anticomplement of a point with respect to a triangle
complement of a point with respect to a triangle
isogonal conjugate of a point with respect to a triangle
isotomic conjugate of a point with respect to a triangle
P-Ceva conjugate of Q with respect to a triangle

conics

Macros for conics associated with a triangle.

centre of a conic
circumconic of a triangle with given centre
inconic of a triangle with given centre
circumconic of a triangle with given perspector
inconic of a triangle with given perspector
perspector of a circumconic of a triangle
perspector of an inconic of a triangle

cabri menus

The following menus include the basic triangle constructs:
complement, anticomplement, isogonal, isotomic and p-ceva conjugates.

centres X(1)-X(10)
centres X(1)-X(20)
centres X(1)-X(10) and conic constructs

For completeness, we give our menu of general constructs for conics.
