Welcome to the
Rocchini's Triangle Geometry

Many thanks to CaRMetal for triangle geometry!

When I was a young boy, the major points of a triangle were only 3: incenter, centroid and circumcenter. Today these points are many and many! I do not like the picture of Parallelepiped Determinant: the human brain confuses skewness for isometric projection. I added the solid's shadow, but the result is not strongly improved. Isogonal counigate trasformation is bijective! Really nice property!

Six circles theorem: the construction of tangent circle is not easy! Try hit! I used a trick: an intersection with a locus...
