I have two easy questions.
Schools Thales' theorem assume that one lines pair is parallel.
Exist anywhere generalization of Thales theorem without this assumption?
I ask about theorem formulated for any four lines on plane and if one of lines pair is parallel then theorem is reduced to Thales' theorem.
How important is this generalization?
Popular Thales' theorem hide or not hide use infinity concept, but geometry without infinity concept is more reality.
If answer on these questions brings difficulty I have a favor, gives someone which can reply these questions.

With best regards Aleksander.A.Krzemie?
