### Cabri macros for triangle centres

**centres**
Macros constructing the first hundred and fifteen centres.

**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.
