- Let ABC be a triangle A'B'C' its medial triangle,

and P a point.

Let Pa,Pb,Pc,P' be the corresponding points of

the triangles AB'C', BC'A', CA'B' and A'B'C', resp.

Which is the locus of P such that:

1. Pa,Pb,Pc,P

2. Pa,Pb,Pc,P'

are concyclic?

Antreas - What is your definition of corresponding points (in two triangles, I

suppose)?
